摘要： A combustor assembly that includes a combustor liner having a centerline axis and defining a combustion chamber there within. A plurality of fuel nozzles extends through the combustion liner. An annular flowsleeve is coupled radially outward from the combustor liner such that an annular flow path is defined between the flowsleeve and the combustor liner. The flowsleeve includes a forward surface that extends between an upper endwall and a lower endwall. The upper endwall is positioned a first distance from the plurality of fuel nozzles. The lower endwall is positioned a second distance from the plurality of fuel nozzles that is different than the first distance.

摘要： A nozzle includes a center body and a shroud circumferentially surrounding at least a portion of the center body to define an annular passage between the center body and the shroud. The nozzle further includes apertures through at least one of the center body or shroud, a plenum in fluid communication with the apertures, and a louvers proximate to the apertures and connected to at least one of the center body or shroud. A method for cooling a nozzle includes flowing a cooling medium through a plenum inside a center body of the nozzle and flowing the cooling medium through apertures in the center body. The method further includes redirecting the cooling medium with louvers to flow the cooling medium across a surface of the center body.
