    Abstract

    A numerical method of analyzing film cooling with a liquid coolant is presented. The model assumes a turbulent boundary-layer flow for the hot gas stream and a Couette flow in the liquid coolant film. A marching procedure is employed for solution of the equations of mass, momentum, enthalpy and species conservation. Numerical results for an air-water system are presented. The effects of flow conditions on the film cooling mechanism are discussed.
