Title: Wavy annular dilution slots for lower emissions

Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     The present application claims the benefit of Indian Patent Application No. 202111050494, filed on Nov. 3, 2021, which is hereby incorporated by reference herein in its entirety. 
     TECHNICAL FIELD 
     The present disclosure relates to a dilution of combustion gases in a combustion chamber of a gas turbine engine. 
     BACKGROUND 
     In conventional gas turbine engines, it has been known to provide a flow of dilution air into a combustion chamber downstream of a primary combustion zone. Conventionally, an annular combustor liner may include both an inner liner and an outer liner forming a combustion chamber between them. The inner liner and the outer liner may include dilution holes through the liners that provide a flow of air (i.e., a dilution jet) from a passage surrounding the annular combustor liner into the combustion chamber. Some applications have been known to use circular holes for providing dilution air flow to the combustion chamber. The flow of air through the circular dilution holes in the conventional combustor mixes with combustion gases within the combustion chamber to provide quenching of the combustion gases. High temperature regions seen behind the dilution jet (i.e., in the wake region of dilution jet) are associated with high NOx formation. In addition, the circular dilution air jet does not spread laterally, thereby creating high temperatures in-between dilution jets that also contribute to high NOx formation.

A person skilled in the relevant art will recognize that other components and configurations may be used without departing from the spirit and scope of the present disclosure. 
     As used herein, the terms “first”, “second”, and “third” may be used interchangeably to distinguish one component from another and are not intended to signify location or importance of the individual components. 
     The terms “upstream” and “downstream” refer to the relative direction with respect to fluid flow in a fluid pathway. For example, “upstream” refers to the direction from which the fluid flows, and “downstream” refers to the direction to which the fluid flows. 
     Various embodiments are discussed in detail below. While specific embodiments are discussed, this is done for illustration purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without departing from the spirit and scope of the present disclosure. 
     In a combustion section of a turbine engine, air flows through an outer passage surrounding a combustor liner, and through an inner passage surrounding the combustor liner. The air generally flows from an upstream end of the combustor liner to a downstream end of the combustor liner. Some of the airflow in both the outer passage and the inner passage is diverted through dilution holes in the combustor liner and into the combustion chamber as dilution air. One purpose of the dilution airflow is to cool (i.e., quench) combustion gases within the combustion chamber before the gases enter a turbine section. However, quenching of the product of combustion from the primary zone must be done quickly and efficiently so that regions of high temperature can be minimized, and thereby NOx emissions from the combustion system can be reduced. 
     The present disclosure aims to reduce the NOx emissions by improving the dilution quenching of the hot combustion gases from the primary combustion zone. According to the present disclosure, a combustor liner includes at least one curved, or wavy dilution opening that has a deflector wall extending into the combustion chamber at a downstream side of the dilution opening. The curved, or wavy, dilution opening may extend circumferentially through the liner about the entire circumference of the liner, or may include curved segments or wavy segments extending through various liner segments, where the liner segments together for an annular type liner. The curved dilution openings or wavy dilution openings introduce the dilution air into the combustion chamber at different axial locations about the circumference of the liner in order to improve mixing for zones with closer equivalence ratios. 
     Referring now to the drawings,  FIG.  1    is a schematic partially cross-sectional side view of an exemplary high by-pass turbofan jet engine  10 , herein referred to as “engine  10 ,” as may incorporate various embodiments of the present disclosure. Although further described below with reference to a turbofan engine, the present disclosure is also applicable to turbomachinery in general, including turbojet, turboprop, and turboshaft gas turbine engines, including marine and industrial turbine engines and auxiliary power units. As shown in  FIG.  1   , engine  10  has a longitudinal or axial centerline axis  12  that extends therethrough from an upstream end  98  to a downstream end  99  for reference purposes. In general, engine  10  may include a fan assembly  14  and a core engine  16  disposed downstream from the fan assembly  14 . 
     The core engine  16  may generally include an outer casing  18  that defines an annular inlet  20 . The outer casing  18  encases or at least partially forms, in serial flow relationship, a compressor section having a booster or low pressure (LP) compressor  22 , a high pressure (HP) compressor  24 , a combustion section  26 , a turbine section, including a high pressure (HP) turbine  28 , a low pressure (LP) turbine  30 , and a jet exhaust nozzle section  32 . A high pressure (HP) rotor shaft  34  drivingly connects the HP turbine  28  to the HP compressor  24 . A low pressure (LP) rotor shaft  36  drivingly connects the LP turbine  30  to the LP compressor  22 . The LP rotor shaft  36  may also be connected to a fan shaft  38  of the fan assembly  14 . In particular embodiments, as shown in  FIG.  1   , the LP rotor shaft  36  may be connected to the fan shaft  38  by way of a reduction gear  40 , such as in an indirect-drive configuration or a geared-drive configuration. In other embodiments, although not illustrated, the engine  10  may further include an intermediate pressure (IP) compressor and a turbine rotatable with an intermediate pressure shaft. 
     As shown in  FIG.  1   , the fan assembly  14  includes a plurality of fan blades  42  that are coupled to and that extend radially outwardly from the fan shaft  38 . An annular fan casing, or nacelle  44 , circumferentially surrounds the fan assembly  14  and/or at least a portion of the core engine  16 . In one embodiment, the nacelle  44  may be supported relative to the core engine  16  by a plurality of circumferentially spaced outlet guide vanes or struts  46 . Moreover, at least a portion of the nacelle  44  may extend over an outer portion of the core engine  16 , so as to define a bypass airflow passage  48  therebetween. 
       FIG.  2    is a cross-sectional side view of an exemplary combustion section  26  of the core engine  16  as shown in  FIG.  1   . As shown in  FIG.  2   , the combustion section  26  may generally include a combustor liner  50  having an inner liner  52 , an outer liner  54 , a cowl  60 , and a dome assembly  56 . The inner liner  52 , the outer liner  54 , and the dome assembly  56  together define a combustion chamber  62 . The combustion chamber  62  may more specifically define various regions, including a primary combustion zone at which initial chemical reaction of a fuel-oxidizer mixture and/or recirculation of combustion gases  86  may occur before flowing further downstream to a dilution zone  72 , where mixture and/or recirculation of the combustion gases  86  and air may occur before flowing into HP and LP turbines  28 ,  30 . The dome assembly  56  extends radially between the outer liner  54  and the inner liner  52 . 
     As shown in  FIG.  2   , the inner liner  52  may be encased within an inner casing  65  and the outer liner  54  may be encased within an outer casing  64 . An outer flow passage  88  is defined between the outer casing  64  and the outer liner  54 , and an inner flow passage  90  is defined between the inner casing  65  and the inner liner  52 . The inner liner  52  may include a plurality of curved slot dilution openings  150  (to be described in more detail below), and the outer liner  54  may also include a plurality of curved slot dilution openings  150 . As will be described in more detail below, the curved slot dilution openings  150  provide a flow of compressed air  82 ( c ) therethrough and into the dilution zone  72  of the combustion chamber  62 . The flow of compressed air  82 ( c ) can thus be utilized to provide quenching of the combustion gases  86  in the dilution zone  72  so as to cool the flow of combustion gases  86  entering the turbine section. 
     During operation of the engine  10 , as shown in  FIGS.  1  and  2    collectively, a volume of air  73 , as indicated schematically by arrows, enters the engine  10  from upstream end  98  through an associated inlet  76  of the nacelle  44  and/or fan assembly  14 . As the volume of air  73  passes across the fan blades  42 , a portion of the air, as indicated schematically by arrows  78 , is directed or routed into the bypass airflow passage  48 , while another portion of the air  80 , as indicated schematically by an arrow, is directed or routed into the LP compressor  22 . Air  80  is progressively compressed as it flows through the LP compressor  22  and the HP compressor  24  towards the combustion section  26 . Referring to  FIG.  2   , the now compressed air  82 , as indicated schematically by an arrow, flows into a diffuser cavity  84  of the combustion section  26  and pressurizes the diffuser cavity  84 . A first portion of the compressed air  82 , as indicated schematically by arrows, compressed air  82 ( a ) flows from the diffuser cavity  84  into a pressure plenum  66 , where it is then swirled by and mixed with fuel, provided by fuel nozzle assembly  70 , by a swirler assembly  58  to generate a swirled fuel-air mixture  85  that is then ignited and burned to generate the combustion gases  86 . A second portion of the compressed air  82 , as indicated schematically by arrows, compressed air  82 ( b ) may be used for various purposes other than combustion. For example, as shown in  FIG.  2   , compressed air  82 ( b ) may be routed into the outer flow passage  88  and into the inner flow passage  90 . A portion of the compressed air  82 ( b ) may then be routed through the curved slot dilution opening  150  (schematically shown as compressed air  82 ( c )) and into the dilution zone  72  of combustion chamber  62  to provide quenching of the combustion gases  86  in dilution zone  72 . The compressed air  82 ( c ) may also provide turbulence to the flow of combustion gases  86  so as to provide better mixing of the compressed air  82 ( c ) with the combustion gases  86 . A similar flow of the compressed air  82 ( c ) from the inner flow passage  90  through the curved slot dilution opening  150  of the inner liner  52  occurs. In addition, or in the alternative, at least a portion of compressed air  82 ( b ) may be routed out of the diffuser cavity  84 . For example, a portion of compressed air  82 ( b ) may be directed through various flow passages (not shown) to provide cooling air to at least one of the HP turbine  28  or the LP turbine  30 . 
     Referring back to  FIGS.  1  and  2    collectively, the combustion gases  86  generated in the combustion chamber  62  flow from the combustion section  26  via a turbine inlet  68  into the HP turbine  28 , thus causing the HP rotor shaft  34  to rotate, thereby supporting operation of the HP compressor  24 . As shown in  FIG.  1   , the combustion gases  86  are then routed through the LP turbine  30 , thus causing the LP rotor shaft  36  to rotate, thereby supporting operation of the LP compressor  22  and/or rotation of the fan shaft  38 . The combustion gases  86  are then exhausted through the jet exhaust nozzle section  32  of the core engine  16  to provide propulsion at downstream end  99 . 
       FIG.  3    is a partial cross-sectional view of a combustor liner  50  taken at plane  3 - 3  shown in  FIG.  1   . As seen in  FIG.  3   , the combustor liner  50  is a generally annular liner that extends circumferentially about the centerline axis  12  of the engine  10 . As it may relate to the combustor liner  50 , the centerline axis  12  may also correspond to a combustor centerline  112 . The combustor liner  50  includes the outer liner  54  and the inner liner  52 . Representative swirler assemblies  58  are shown as being circumferentially spaced about the combustor centerline  112 . With respect to each swirler assembly  58 , a portion of the combustor liner  50  may be considered as a segment of the combustor liner  50 . That is, the combustor liner  50  may be considered to include multiple segments (e.g., a first combustor liner segment  129  and a second combustor liner segment  131 ) circumferentially about the combustor centerline  112 , where each segment corresponds to a respective swirler assembly  58 . For example, the first combustor liner segment  129  may be associated with a first segment swirler assembly  58 ( a ), and may be defined between a segment boundary line  134  and a segment boundary line  136 , which extend radially outward from combustor centerline  112  and may be equally angularly spaced apart from a center  144  of the first segment swirler assembly  58 ( a ). Similarly, the second combustor liner segment  131  may be associated with the second segment swirler assembly  58 ( b ), and may be defined between segment boundary line  134  and a segment boundary line  138 . The second combustor liner segment  131  is adjacent to the first combustor liner segment  129 . The first combustor liner segment  129  includes a first segment outer liner  130  and a first inner liner segment  140 , while the second combustor liner segment  131  includes a second segment outer liner  132  and a second inner liner segment  142 . Of course, both the outer liner  54  and the inner liner  52  may be formed as one continuous annular liner rather than multiple segments that are joined together, but, for the purposes of the discussion below relating to the dilution openings, both the outer liner  54  and the inner liner  52  will be considered to be segmented. 
       FIG.  4    depicts a partial cross-sectional view of a segment of the combustor liner  50 , according to an aspect of the present disclosure.  FIG.  5    is a perspective view of the segment of the combustor liner  50  shown in  FIG.  4   . The segment of the combustor liner  50  shown in  FIGS.  4  and  5    may correspond to, for example, the first combustor liner segment  129 . In  FIGS.  4  and  5   , the first segment swirler assembly  58 ( a ) is depicted merely for reference purposes. Referring to  FIG.  4   , the combustor liner  50  defines an axial direction (L), which may be parallel to the combustor centerline  112 , a radial direction (R), which extends generally perpendicular to the combustor centerline  112 , and a circumferential direction (C) about a combustor centerline  112 . The combustor liner  50  includes the outer liner  54  that, as described above, includes a plurality of outer liner segments (e.g., first segment outer liner  130  and second segment outer liner  132  ( FIG.  3   )) connected together so as to extend annularly about the combustor centerline  112 . The first segment outer liner  130  extends from an outer liner upstream end  100  to an outer liner downstream end  102  and includes an outer liner dilution zone  108  between the outer liner upstream end  100  and the outer liner downstream end  102 . The first segment outer liner  130  has an outer liner cold surface side  122  adjacent to the outer flow passage  88 , and an outer liner hot surface side  124  adjacent to the combustion chamber  62 . As was described above, a portion of the compressed air  82 ( b ) flows in the outer flow passage  88 , and the compressed air  82 ( b ) flows from the outer liner upstream end  100  toward the outer liner downstream end  102 , thereby defining an outer flow direction  92  that extends in the axial direction (L). The first segment outer liner  130  further includes at least one first segment outer liner slotted dilution opening  114  therethrough in the outer liner dilution zone  108 . Various arrangements of the first segment outer liner slotted dilution opening  114  will be described in more detail below. In  FIGS.  4  and  5   , however, the first segment outer liner slotted dilution opening  114  is shown as a curved slot opening ( FIG.  5   ), which will be described in more detail below. The first segment outer liner  130  is further seen to include a first segment outer liner deflector wall  116  extending radially inward from the outer liner hot surface side  124  adjacent to a downstream side  146  of the first segment outer liner slotted dilution opening  114 . The first segment outer liner deflector wall  116  generally follows the contour of the downstream side  146  of the first segment outer liner slotted dilution opening  114 . Various arrangements of the first segment outer liner deflector wall  116  will be described in more detail below. With the first segment outer liner slotted dilution opening  114 , and the first segment outer liner deflector wall  116 , a portion (shown schematically as compressed air  82 ( c )) of the compressed air  82 ( b ) flowing in the outer flow passage  88  flows through the first segment outer liner slotted dilution opening  114  and is deflected or guided by the first segment outer liner deflector wall  116  radially inward into the dilution zone  72  of the combustion chamber  62 . While the term deflector wall may be utilized herein, it is noted that the deflector wall  116  acts as a fence for hot gases flowing within the combustion chamber  62 , and also acts as a guide or support wall for guiding a flow of the compressed air  82 ( c ) through the first segment outer liner slotted dilution opening  114  into the combustion chamber  62 . Thus, the deflector wall  116  may not necessarily merely deflect the hot gases or the air  82 ( c ), but rather, may act as a guide for the flow of each instead. 
     The combustor liner  50  also includes the inner liner  52  that, as described above, includes a plurality of inner liner segments (e.g., first inner liner segment  140  and second inner liner segment  142  ( FIG.  3   )) connected together so as to extend annularly about the combustor centerline  112 . The first inner liner segment  140  extends from an inner liner upstream end  104  to an inner liner downstream end  106 , and includes an inner liner dilution zone  110  between the inner liner upstream end  104  and the inner liner downstream end  106 . The first inner liner segment  140  has an inner liner cold surface side  126  adjacent to the inner flow passage  90 , and an inner liner hot surface side  128  adjacent to the combustion chamber  62 . As was described above, a portion of the compressed air  82 ( b ) flows in the inner flow passage  90 , and the compressed air  82 ( b ) flows from the inner liner upstream end  104  toward the inner liner downstream end  106 , thereby defining an inner liner flow direction  94  that extends in the axial direction (L). The first inner liner segment  140  further includes at least one first segment inner liner slotted dilution opening  118  therethrough in the inner liner dilution zone  110 . Various arrangements of the first segment inner liner slotted dilution opening  118  will be described in more detail below. In  FIG.  4   , however, the first segment inner liner slotted dilution opening  118  is shown as a curved slot opening, which will be described in more detail below. The first inner liner segment  140  is further seen to include a first segment inner liner deflector wall  120  extending radially outward from the inner liner hot surface side  128  adjacent to a downstream side  148  of the first segment inner liner slotted dilution opening  118 . As seen in  FIG.  5   , the first segment inner liner deflector wall  120  generally follows the contour of the downstream side  148  of the first segment inner liner slotted dilution opening  118 . Various arrangements of the first segment inner liner deflector wall  120  will be described in more detail below. As seen in  FIG.  4   , with the first segment inner liner slotted dilution opening  118 , and the first segment inner liner deflector wall  120 , a portion (shown schematically as compressed air  82 ( c )) of the compressed air  82 ( b ) flowing in the inner flow passage  90  flows through the first segment inner liner slotted dilution opening  118  and is deflected by the first segment inner liner deflector wall  120  radially outward into the dilution zone  72  of the combustion chamber  62 . 
     While the foregoing description related to the first combustor liner segment  129  of the combustor liner  50 , it can be appreciated that the same arrangement of the first combustor liner segment  129  is applicable to the second combustor liner segment  131  of the combustor liner  50 , and all other segments of the combustor liner  50 . 
     Various arrangements of slotted dilution openings through the outer liner  54  and the inner liner  52  will now be described with regard to  FIGS.  6  to  15   . The following descriptions will be made with regard to slotted dilution openings through the outer liner  54 , and, in particular, with regard to slotted dilution openings through the first segment outer liner  130 , and, where applicable, the second segment outer liner  132 . It can be appreciated, however, that the same slotted dilution openings described below are applicable to all remaining outer liner segments of the combustor liner  50 . In addition, the same slotted dilution openings described below are applicable to the first inner liner segment  140 , and where applicable, the second inner liner segment  142 , as well as all other inner liner segments. Thus, a description of the remaining outer liner segments, and all of the inner liner segments, will be omitted for the sake of brevity. 
       FIG.  6    depicts a plan view of an exemplary first segment outer liner  130 , taken at view A-A of  FIG.  4   . As seen in  FIG.  6   , the first segment outer liner  130  extends circumferentially between the segment boundary line  134  and the segment boundary line  136 , and extends in the axial direction (L) from the outer liner upstream end  100  to the outer liner downstream end  102 , and includes the outer liner dilution zone  108  therebetween. Within the outer liner dilution zone  108 , a curved slot dilution opening  150  extends through the first segment outer liner  130 . The curved slot dilution opening  150  extends in the circumferential direction (C) across the first segment outer liner  130  from the segment boundary line  134  to the segment boundary line  136 . The curved slot dilution opening  150 , however, may not extend completely across the width  171  of the first segment outer liner  130 , but may instead extend partially across the width of the first segment outer liner  130  so as to form a curved slot dilution opening  150 . In  FIG.  6   , the curved slot dilution opening  150  is shown to be formed as a concave curved slot dilution opening  151  with respect to the outer flow direction  92  or the inner flow direction  94 . However, the curved slot dilution opening  150  may instead be formed as a convex curved slot dilution opening  156  with respect to the outer flow direction  92  or the inner flow direction  94 . The curved slot dilution opening  150  includes a deflector wall  152  that, as seen by the hidden lines, generally follows the curved contour of a downstream side  154  of the curved slot dilution opening  150 . A similar deflector wall  158 , as seen by the hidden lines, may be provided to the convex curved slot dilution opening  156 . 
     In  FIG.  6   , the curved slot dilution opening  150  is seen to be generally arranged symmetrical about a first segment centerline  170 . For example, a first distance  196  from the outer liner upstream end  100  of the first segment outer liner  130  to a first end  192  of the curved slot dilution opening  150  and to a second end  194  of the curved slot dilution opening  150  is the same. On the other hand, an arrangement of a curved slot dilution opening  198  may be implemented in which a second end  200 , as seen by the hidden lines, is downstream a second distance  202  from the first end  192  at the first distance  196 . Thus, the curved slot dilution opening  198  may be skewed rather than being symmetrical about the first segment centerline  170 . 
       FIG.  7    is a partial cross-sectional view of the curved slot dilution opening  150  and the deflector wall  152  taken at plane  7 - 7  of  FIG.  6   . While  FIGS.  6  and  7    depict an arrangement for the first outer liner segment  130 , it can be readily understood that a similar mirror image arrangement may be implemented in the first segment inner liner  140 . Thus, the description of  FIGS.  6  and  7   , as well as the description of  FIGS.  8  to  14   , may be implemented in either or both of the outer liner  54  and/or the inner liner  52 . As seen in  FIG.  7   , the deflector wall  152  extends in the radial direction radially inward from the outer liner hot surface side  124  into the dilution zone  72  of the combustion chamber  62  from the downstream side  154  of the curved slot dilution opening  150 . For the first inner liner segment  140 , the deflector wall  152  extends in the radial direction radially outward from the inner liner hot surface side  128  into the dilution zone  72  of the combustion chamber  62 . A height  160  of the deflector wall  152  may be varied to obtain a desired amount of mixing of the compressed air  82 ( c ) with the combustion gases  86  within the dilution zone  72 . The deflector wall  152  shown in  FIG.  7    is shown as generally being perpendicular to outer liner hot surface side  124  and the inner liner hot surface side  128 , but the deflector wall  152  may be angled instead. For example, an upstream angled deflector wall  162 , as seen by the hidden lines, may be angled in an upstream direction toward the outer liner upstream end  100  (or the inner liner upstream end  104 ) of the outer liner  54  (or the inner liner  52 ) at an outer/inner liner deflector wall upstream angle  164 . Alternatively, a downstream angled deflector wall  166 , as seen by the hidden lines, may be angled in a downstream direction toward the outer liner downstream end  102  (or the inner liner downstream end  106 ) of the outer liner  54  (or the inner liner  52 ) at a downstream angle  168 . The outer/inner liner deflector wall upstream angle  164  may range from zero to fifty-five degrees in the upstream direction, while the downstream angle  168  may range from zero to forty-five degrees. Of course, upstream angle  164  and the downstream angle  168  are not limited to the foregoing ranges, and other angles may be implemented instead based on a desired amount of mixing to be achieved for the dilution air. 
     Also shown in  FIG.  7    is a bridge member  204  that spans across the curved slot dilution opening  150 . That is, in a case when the slotted dilution opening extends circumferentially across the first segment from segment boundary line  134  to the segment boundary line  136 , and when the slotted dilution opening of each segment of the outer liner  54  is connected with the slotted dilution opening of adjacent segments, the outer liner  54  may be split axially into two sections: an outer liner upstream section  206  and an outer liner downstream section  208 . The bridge member  204  is implemented to connect the two sections. For example, consider a case when each outer liner segment includes the curved slot dilution opening  150  of the  FIG.  6    arrangement. In this case, the second end  194  of the curved slot dilution opening  150  in the first combustor liner segment  129  is aligned with and connects with a second end  194  of a curved slot dilution opening  150  in the second combustor liner segment  131 , and so on, for each segment about the entire circumference of the outer liner  54 . The connected curved slotted dilution openings  150  of each segment results in a separation of the outer liner into the outer liner upstream section  206  and the outer liner downstream section  208 . Thus, to connect the outer liner upstream section  206  and the outer liner downstream section  208  together, a plurality of the bridge members  204  may be included about the circumference of the outer liner  54 . For instance, with respect to the first combustor liner segment  129  and the second combustor liner segment  131 , a bridge member  204  may be provided at the intersection of the two segments (i.e., at segment boundary line  134 ) across the curved slot dilution opening  150 . 
       FIG.  8    is a plan view of another first segment outer liner  130 , taken at A-A in  FIG.  4   , according to another aspect of the present disclosure. In  FIG.  8   , the first segment outer liner  130  defines a first segment centerline  170  centered between the segment boundary line  134  and the segment boundary line  136 . The  FIG.  8    arrangement of the first segment slotted dilution opening includes multiple curved slot dilution openings connected together in the same segment. More particularly, the slotted dilution opening of  FIG.  8    includes a first curved slot dilution opening  172  connected with a second curved slot dilution opening  174 , extending in the circumferential direction (C) across the first segment outer liner  130  from the segment boundary line  134  to the segment boundary line  136 . The first curved slot dilution opening  172  is seen to be a concave curved slot dilution opening, similar to the concave curved slot dilution opening  150 , but extending from the segment boundary line  134  to the first segment centerline  170 . Similarly, the second curved slot dilution opening  174  is seen to be a concave curved slot dilution opening similar to the concave curved slot dilution opening  150 , but extends from the first segment centerline  170  to the segment boundary line  136 . The first curved slot dilution opening  172  and the second curved slot dilution opening  174  are connected at the first segment centerline  170 . A deflector wall  176  generally follows the contour of the downstream side  178  of the first curved slot dilution opening  172  and the downstream side  180  of the second curved slot dilution opening  174 . It can be appreciated that, while the first curved slot dilution opening  172  and the second curved slot dilution opening  174  are shown as concave curved slot dilution openings with respect to the outer flow direction  92 , they both may be convex curved slot dilution openings instead, similar to the convex curved slot dilution opening  156  of  FIG.  6   . Alternatively, as seen in  FIG.  9   , a first convex curved slot dilution opening  182  may be implemented in conjunction with a second concave curved slot dilution opening  184  within the first segment outer liner  130 . A deflector wall  186  follows the contour of the downstream side  188  of the first convex curved slot dilution opening  182  and the downstream side  190  of the second concave curved slot dilution opening  184 . 
     In each of the foregoing aspects, the slotted dilution opening was described as being a curved slot dilution opening. However, the slotted dilution opening may, instead, be formed of linear slot segments arranged in the circumferential direction.  FIG.  10    depicts an example of a first segment outer liner  130  that includes linear slot segments. In  FIG.  10   , a linear slot dilution opening  230  is seen to include a linear slot dilution opening middle segment  210 , a first linear slot dilution opening outer segment  212  and a second linear slot dilution opening outer segment  214 . The linear slot dilution opening middle segment  210  may generally extend in the circumferential direction across a middle section  224  of the first segment outer liner  130 . The first linear slot dilution opening outer segment  212  may extend across a first outer section  226  of the first segment outer liner  130  from the middle section  224  to the segment boundary line  136  of the first segment outer liner  130 , and may extend both in the circumferential direction and axially downstream at an angle  218 . The second linear slot dilution opening outer segment  214  may extend across a second outer section  228  of the first segment outer liner  130  from the middle section  224  to the segment boundary line  134  of the first segment outer liner  130 , and may extend both in the circumferential direction and axially upstream at an angle  220 . Alternatively, a second linear slot dilution opening outer segment  216  may be provided and may extend across the second outer section  228  of the first segment outer liner  130  from the middle section  224  to the segment boundary line  136  of the first segment outer liner  130 , and may extend both in the circumferential direction and axially downstream at an angle  222 . 
     While the linear slot dilution opening  230  is shown in  FIG.  10    as extending circumferentially across the entirety of the first segment outer liner  130  from the segment boundary line  134  to the segment boundary line  136 , the linear slotted dilution opening does not need to extend circumferentially across the entirety of the first segment outer liner  130 . Rather, the linear slotted dilution opening may, for example, include only the linear slot dilution opening middle segment  210 . In this aspect, the linear slot dilution opening middle segment  210  may take other forms than merely being a straight line extending circumferentially. For instance, the linear slot dilution opening middle segment  210  may instead form a V-shaped slotted dilution opening  232 , with an apex  234  of the V-shaped slotted dilution opening  232  being on an upstream side of the V-shaped slotted dilution opening  232 , as seen by the hidden lines. Of course, the V-shaped slotted dilution opening  232  may be inverted from that shown in  FIG.  10   . 
     Each of the foregoing arrangements of slotted dilution openings in  FIGS.  4  to  10    generally result in a circumferentially continuous slotted dilution opening through the outer liner  54 . That is, the slotted dilution opening extends circumferentially about the combustor centerline  112  through the outer liner  54  so as to result in the outer liner upstream section  206  and the outer liner downstream section  208 , connected together with the circumferentially spaced bridge members  204 . In contrast, the following description will present aspects of the present disclosure where the slotted dilution opening is not circumferentially continuous, but rather, is segment-based. In other words, the slotted dilution opening of one segment is not connected to the slotted dilution opening of an adjacent combustor liner segment. 
       FIG.  11    depicts an exemplary first segment outer liner according to yet another aspect of the present disclosure. In  FIG.  11   , a plurality of rows of slotted dilution openings are provided through the first segment outer liner  130 . A first row  236  includes a plurality of first row curved slot dilution openings  240 ,  242 , and  244 , and a second row  238 , downstream of the first row  236 , includes a plurality of second row curved slot dilution openings  246  and  248 . Each of the first row curved slot dilution openings  240 ,  242 , and  244  are shown as a concave curved slot dilution opening, with respect to the outer flow direction  92 . Each of the second row curved slot dilution openings  246  and  248  are also shown as concave curved slot dilution openings, with respect to the outer flow direction  92 . Of course, the first row curved slot dilution openings  240 ,  242 , and  244  may be convex curved slot dilution openings instead of concave, and the second row curved slot dilution openings  246  and  248  may be concave curved slot dilution openings Alternatively, as seen in  FIG.  11   , the first row curved slot dilution openings  240 ,  242 , and  244  may be concave curved slot dilution openings, while the second row  238  may include second row curved slot dilution openings  250  and  252  (shown with hidden lines) implemented as convex curved slot dilution openings While not shown in  FIG.  11   , each of the first row curved slot dilution openings  240 ,  242 , and  244  may include a respective deflector wall extending into the combustion chamber  62  at their downstream side, and each of the second row curved slot dilution openings  250  and  252  may also include a respective deflector wall extending into the combustion chamber at their respective downstream sides. 
     In addition, as seen in  FIG.  11   , the first row curved slot dilution openings  240 ,  242 , and  244 , may be spaced apart from one another in the circumferential direction, and the second row curved slot dilution openings  250  and  252  may also be spaced apart from one another in the circumferential direction. For example, the first row curved slot dilution opening  240  may be implemented in a middle section  254  of the first segment outer liner  130 , the first row curved slot dilution opening  242  may be implemented in a first outer section  258  disposed between the middle section  254  and the segment boundary line  134 , and the first row curved slot dilution opening  244  may be implemented in a second outer section  256  between the middle section  254  and the segment boundary line  136 . A spacing distance  260  between, for example, the first row curved slot dilution opening  240  and the first row curved slot dilution opening  244 , may be set based on a desired amount dilution air flow to be provided from the outer flow passage  88  to the dilution zone  72  of the combustion chamber  62 . 
     Additionally, each of the curved slot dilution openings of the second row may be circumferentially offset (or staggered) with respect to the first row curved slot dilution openings. For example, as shown in  FIG.  11   , the second row curved slot dilution opening  246  may be arranged to extend from the middle section  254  into the second outer section  256  so that a first end  262  of the second row curved slot dilution opening  246  overlaps circumferentially with the first row curved slot dilution opening  244 , and a second end  264  of the second row curved slot dilution opening  246  overlaps circumferentially with the first row curved slot dilution opening  240 . 
     As seen in  FIG.  12   , is an arrangement of slotted dilution openings between segments of the outer liner, according to another aspect of the present disclosure. In  FIG.  12   , a concave curved slot dilution opening  265  is included in the first segment outer liner  130 , and a concave curved slot dilution opening  267  is included in the second segment outer liner  132 . Unlike the concave curved slot dilution opening  150  of  FIG.  6   , which extends circumferentially across the entirety of the first segment outer liner  130  from the segment boundary line  134  to the segment boundary line  136 , the concave curved slot dilution opening  265  of  FIG.  11    does not extend the full distance between the segment boundary line  134  and the segment boundary line  136 . Rather, a first gap  272  is defined between a first end  268  of the concave curved slot dilution opening  265  and the segment boundary line  136 . Similarly, a second gap  274  is defined between a second end  270  of the concave curved slot dilution opening  265  and the segment boundary line  134 . With the  FIG.  12    implementation, to achieve a circumferentially continuous slotted dilution opening about the outer liner  54 , an outer liner connecting dilution opening  266  is provided to connect the concave curved slot dilution opening  265  of the first segment outer liner  130  with the concave curved slot dilution opening  267  of the second segment outer liner  132 . The outer liner connecting dilution opening  266  is shown in  FIG.  12    as a generally linear slotted dilution opening extending in the circumferential direction. As with the previous aspects, the concave curved slot dilution opening  265  and the concave curved slot dilution opening  267  each includes a deflector wall (not shown) along the contour of their respective downstream sides. The outer liner connecting dilution opening  266  may also include a deflector wall (not shown), or the deflector wall may be omitted from the outer liner connecting dilution opening  266 . Of course, the concave curved slot dilution opening  265  and the concave curved slot dilution opening  267  could be implemented with both being convex curved slot dilution openings (not shown) instead, or one could be concave as shown in  FIG.  11    and the other convex (not shown). 
       FIG.  13    depicts another arrangement of slotted dilution openings between segments of the outer liner, according to still another aspect of the present disclosure. The  FIG.  13    arrangement is somewhat similar to the  FIG.  12    arrangement, but, in  FIG.  13   , a convex curved slot connecting dilution opening  276  is implemented between the first segment outer liner  130  and the second segment outer liner  132 . With the  FIG.  13    arrangement, a radius of the concave curved slot dilution opening  265  may be smaller than that of the concave curved slot dilution opening  265  of  FIG.  12   . As such, the first gap  272  between the segment boundary line  136  and the first end  268  of the concave curved slot dilution opening  265  may be greater than that of  FIG.  12   , and the second gap  274  between the segment boundary line  134  and the second end  270  of the concave curved slot dilution opening  265  may be greater than that of  FIG.  12   . With the implementation of the convex curved slot connecting dilution opening  276 , a sine wave type continuous dilution opening may be formed through the outer liner  54  about its entire circumference. Again, while not shown in  FIG.  13   , each respective curved slot dilution opening may include a respective deflector wall along the contour of their respective downstream sides. 
       FIG.  14    depicts yet another arrangement of slotted dilution openings between segments of the outer liner, according to still yet another aspect of the present disclosure. In  FIG.  14   , an arrangement of slotted dilution openings is implemented so as to provide for a single piece outer liner (i.e., an outer liner that does not require the bridge member  204  to connect an upstream section and a downstream section of the outer liner), unlike the aspects of  FIGS.  12    and  13  where the slotted dilution opening is a circumferentially continuous slotted opening about the entire circumference of the outer liner  54 . In  FIG.  14   , the first segment outer liner  130  may include a generally S-shaped slotted dilution opening  278 , where a first end  282  of the S-shaped slotted dilution opening  278  may begin at the segment boundary line  134 , and a second end  284  of the S-shaped slotted dilution opening  278  may extend across the segment boundary line  136  into a third segment outer liner  292  of a third segment  290  ( FIG.  3   ) adjacent to the first segment outer liner  130 . Similarly, the second segment outer liner  132  is seen to include an S-shaped slotted dilution opening  280 , where a first end  286  of the S-shaped slotted dilution opening  280  begins at the segment boundary line  138  and a second end  288  extends across the segment boundary line  134  into the first segment outer liner  130 . The second end  288  of the S-shaped slotted dilution opening  280  may be disposed upstream of the first end  282  of the S-shaped slotted dilution opening  278  if the first segment outer liner  130  so as to offset the S-shaped slotted dilution opening  278  and the S-shaped slotted dilution opening  280 . 
       FIG.  15    depicts another arrangement of slotted dilution openings between segments of the outer liner, according to still yet another aspect of the present disclosure. The arrangement of  FIG.  15   , like the arrangement of  FIG.  14   , depicts another example of discontinuous slotted dilution openings between segments so as to provide for a single piece outer liner  54 . In  FIG.  15   , the first segment outer liner  130  is seen to include a first segment convex curved slot dilution opening  294  and the second segment outer liner  132  is seen to include a second segment convex curved slot dilution opening  296 . The first segment convex curved slot dilution opening  294  may be centrally located between the segment boundary line  134  and the segment boundary line  136 . For example, the first gap  272  between the segment boundary line  136  and a first end  308  of the first segment convex curved slot dilution opening  294  may be the same as the second gap  274  between the segment boundary line  134  and a second end  310  of the first segment convex curved slot dilution opening  294 . A similar alignment is provided for the second segment convex curved slot dilution opening  296  with respect to the segment boundary line  134  and the segment boundary line  138 . Circumferentially, the first segment convex curved slot dilution opening  294  and the second segment convex curved slot dilution opening  296  are seen to be arranged in a first row  300 . 
     An outer liner concave curved slot connecting dilution opening  298  is provided between the first segment outer liner  130  and the second segment outer liner  132 . As seen in  FIG.  15   , the outer liner concave curved slot connecting dilution opening  298  is provided in a second row  302  and includes a first portion  297  that is provided in the first combustor liner segment  129  and a second portion  299  that is provided in the second combustor liner segment  131 . The second row  302  also includes an outer liner concave curved slot connecting dilution opening  312  that connects the first segment outer liner  130  with the adjacent third segment outer liner  292 . The second row  302  further includes an outer liner concave curved slot connecting dilution opening  314  that connects the second segment outer liner  132  with an adjacent fourth segment outer liner  316  (see  FIG.  3   ). As shown in  FIG.  15   , while the first segment convex curved slot dilution opening  294  and the second segment convex curved slot dilution opening  296  are provided in the first row  300 , and the outer liner concave curved slot connecting dilution opening  298  is provided in the second row  302 , the dilution openings of the first row  300  and the dilution openings of the second row  302  overlap one another both circumferentially and axially. For example, the first segment convex curved slot dilution opening  294  and the outer liner concave curved slot connecting dilution opening  298  overlap one another axially in an axial overlap region  304 , and they also overlap one another circumferentially in a circumferential overlap region  306 . A similar axial and circumferential overlap is provided between the second segment convex curved slot dilution opening  296  and the outer liner concave curved slot connecting dilution opening  298 . While not shown in  FIG.  15   , a respective deflector wall may be provided for each of the dilution openings. Alternatively, a deflector wall may be provided for the dilution openings in the second row  302 , but not for the dilution openings in the first row  300 . 
     While the foregoing description relates generally to a gas turbine engine, it can readily be understood that the gas turbine engine may be implemented in various environments. For example, the engine may be implemented in an aircraft, but may also be implemented in non-aircraft applications such as power generating stations, marine applications, or oil and gas production applications. Thus, the present disclosure is not limited to use in aircraft. 
     Further aspects of the present disclosure are provided by the subject matter of the following clauses.
