    Abstract: A combustor assembly includes an inner and an outer liner defining a combustion chamber. The inner and outer liner includes a plurality of cooling holes that are spaced a specified distance apart. The cooling holes include a specified inclination angle (54) and circumferential angle (56). A first group (58) of cooling holes is spaced apart according to a uniform geometric pattern and density. A second group (62; 68; 72) disposed between the first group (58) and some structural feature (32; 38; 40) within the liner assembly is disposed at a non-uniform pattern and a hole density equal to the density of the first group of cooling holes. The non-uniform cooling hole arrangement increases cooling flow effectiveness to accommodate local disturbances and thermal properties.
