Abstract
A combustion liner for a combustor of a turbine engine includes a plurality of undulations which extend around the exterior circumference of the combustion liner. A plurality of rows of cooling holes are formed through the combustion liner. Each row of cooling holes is located in one of the undulations which extends around the exterior circumference of the combustion liner. The cooling holes admit a flow of cooling air into the interior of the combustion liner. The cooling holes are located and oriented to help the flow of cooling air form a film along the inner surface of the combustion liner.
