Abstract Film cooling is widely used to protect modern gas turbine blades and vanes from the ever increasing inlet temperatures. Film cooling
involves a very complex turbulent flow-field, the characterization of which is necessary for reliable and economical design. Several
experimental studies have focused on gas turbine blade, vane and end-wall film cooling over the past few decades. Measurements
of heat transfer coefficients, film cooling effectiveness values and heat flux ratios using several different experimental methods have
been reported. The emphasis of this current review is on the Pressure Sensitive Paint (PSP) mass transfer analogy to determine the
film cooling effectiveness.… More >
