CONVECTION COOLING AT LOW EFFUSION DENSITY REGION OF COMBUSTOR PANEL

Abstract: a combustor for a gas turbine engine includes a combustion chamber defined between an inner shell and an outer shell. the combustor further includes a bulkhead extending between the inner shell and the outer shell. the combustor further includes a liner panel mounted to one of the inner shell and the outer shell aft of the bulkhead. the liner panel includes a first section including a first plurality of effusion holes. a first portion of the first plurality of effusion holes extends in a substantially circumferential direction. a second portion of the first plurality of effusion holes, disposed forward of the first portion, transitions from the substantially circumferential direction toward a substantially forward direction. a third portion of the first plurality of effusion holes, disposed aft of the first portion, transitions from the substantially circumferential direction to a substantially aft direction.
