Claim 17:
18. A method of atomizing a fluid, the method comprising:
coupling an inner member to a first outer member, the inner member having an axis and defining an interior first-fluid flowpath extending from an upstream end of the inner member to a downstream end of the inner member along the axis, the first outer member positioned radially outward from a portion of the inner member proximate the upstream end of the inner member, the first outer member defining a second-fluid supply conduit;
coupling the inner member to a second outer member, the second outer member positioned radially inward from a portion of the first outer member and radially outward of the inner member, the second outer member extending axially from the first outer member to the downstream end of the inner member, wherein
the inner member, the first outer member, and the second outer member define a second-fluid flowpath extending from the second-fluid supply conduit to the downstream end of the inner member,
the second-fluid flowpath comprising
a conduit extending from an entry plenum in fluid communication with the second-fluid supply conduit to an exit plenum spaced circumferentially from and axially downstream of the entry plenum,
an annulus downstream from and in fluid communication with the exit plenum, and
a discharge plenum downstream from and in fluid communication with the annulus, wherein
the annulus extends axially between the inner member and the second outer member from exit plenum to the discharge plenum, and
the entry plenum is disposed between (1) a downstream end of the first outer member and (2) the inner member; and

directing the fluid from the second-fluid supply conduit through the second-fluid flowpath.
