A combustor assembly (10) includes an inner and outer liner (16,18) defining a combustion chamber (22). The inner and outer liners (16,18) include a plurality of cooling holes (36) spaced a specified distance apart. The cooling holes (36) include first, second and third groups (44,46,48). The first group (44) of cooling holes (36) is the most densely spaced, followed by the second group (46) and then the third group (48). The first group (44) of cooling holes (36) begin upstream of a leading edge (50) of a large opening (50) and terminates downstream of the leading edge (50). The increased density of cooling holes (36) adjacent the large openings (38) provide increased cooling airflow in areas where cooling may be affected by local disturbances in cooling airflow.
