Journal of Engineering Physics and Thermophysics Aims and scope

Abstract

Physical simulation of a thermal screen behin a row of standard orifices on the surface of the leading edge of a turbine blade is carried out by the heat and mass analogy method. A procedure is proposed for calculating the efficiency of thermal screens behind rows of orfices on the surface with a geometry typical of cooling systems on the leading edges of turbine blades.
