Solving a conjugate problem of heat transfer, we consider the influence of the differences of thermal diffusivity coefficient of cooling air on the efficiency of film cooling, cooling performance at blowing the cooling air from the cylindrical and fan-shaped holes and in the presence of a pressure gradient in the external flow.
