Claim:
A combustor liner suitable for use in a turbine engine, said combustor liner comprising: a nonplanar inner liner; a nonplanar outer liner; and a liner dome attached to said inner liner and to said outer liner so as to form an assembly enclosing a combustion zone, said liner dome having an exterior cool surface for intercepting a cooling air stream and an interior hot surface, said liner dome further having an array of effusion holes therethrough for passing cooling air from said cooling air stream into said combustion zone, wherein a local region of said array of effusion holes includes a plurality of upstream-pointed effusion holes, said upstream-pointed effusion holes having orientations obtuse to the direction of a main flow of gases in said combustion zone; wherein said nonplanar inner liner comprises an array of inner liner effusion holes therethrough, a local region of said array of inner liner effusion holes in said inner liner including a plurality of upstream-pointed inner liner effusion holes oriented such that each said upstream-pointed inner liner effusion hole has an orientation obtuse to the direction of said main flow.
