Abstract:
1. A method of assembling a combustor assembly, said method comprising: providing a combustor liner having a centerline axis and defining a combustion chamber therein; coupling an annular flowsleeve radially outward from the combustor liner such that an annular flow path is defined substantially circumferentially between the flowsleeve and the combustor liner; and orienting the flowsleeve such that a plurality of inlets formed within the flowsleeve are positioned to inject cooling air in a substantially axial direction into the annular flow path to facilitate increasing dynamic pressure recovery within the flow path, wherein the inlets are oriented substantially parallel to the centerline axis and each has a length that is longer than a diameter of the inlet; the inlets being positioned radially outside a gap receiving air from a transition piece.
