NOVELTY - The assembly (200) has an annular pilot mixer housing (212) separating a pilot mixer (210) from a main mixer (220) and forming a cavity (208), where the annular housing has a forward portion (202) and an aft portion (204). A fuel nozzle (152) is surrounded by the forward portion of the housing. A bulkhead wall (214) is located downstream of the fuel nozzle and connects the forward portion of the housing to the aft portion of the housing, where the wall is perpendicular to the aft portion of the housing and forms a corner (206) between the aft portion of the housing and the wall.    USE - Mixer assembly for a gas turbine engine i.e. turbofan utilized in powering modern aircraft and sea vessels, generating electrical power, and industrial applications.    ADVANTAGE - The assembly comprises a corner recirculation zone that allows complete combustion of the fuel before the fuel leaves the annular pilot mixer housing of the pilot mixer and enters the combustion chamber, thus minimizing potential for producing carbon monoxide (CO) and unburned hydrocarbons (UHC) based on improper or incomplete combustion. The assembly comprises a set of holes circumferentially distributed in, and extending transversally through the pilot mixer bulkhead wall proximate the inner surface of the aft portion of the annular pilot mixer housing such that a portion of the air passing through the another set of holes in the pilot mixer forward wall also passes through the former set of holes, so that film cooling of the inner surface of the housing is provided, thus providing adequate cooling of the pilot mixer and avoiding excessive heat that damage the assembly. The assembly comprises a corner recirculation zone effectively recirculating hot products in the corner of the pilot mixer cavity, thus maintaining stability of the pilot mixer.
