Beschreibung
Zusammenfassung:	A gas turbine engine includes a combustion system (200). The combustion system includes a combustor positioned in a chamber created by an outer wall. A compressor, such as a centrifugal compressor provides a flow of compressed air into the chamber along an inner surface of the outer wall since an inlet for the flow of compressed air is outboard of the combustor. The pressurized flow of air may is redirected by a cowl (552) included in the chamber. The cowl ncludes a collar (516) defining a notch (504) in the cowl. The collar redirects the flow of pressurized air so as to minimize a high velocity component of the flow of pressurized air flowing radially toward a central axis of the engine prior to entering a head (226) of a fuel nozzle (224) included in the combustion system.
