ABSTRACT:
A method enables a gas turbine engine including a combustor to be operated. The combustor includes a mixer assembly including an air swirler, a premixer, a dome plate, and a heat shield. The method comprises discharging fluids from the air swirler into the premixer, and directing cooling fluids through a cooling opening defined in at least one of the swirler and the dome plate towards an upstream side of the heat shield for impingement cooling of the heat shield.
