The results show that, for the present investigation conditions, the filmcooling effectiveness will be increased with the increase of blowing ratios and the diameter of filmhole;
Using the method of heat-mass transfer analogy, experimental research was carried on to investigate adiabatic film effectiveness of inclined multi-hole full-coverage filmcooling.
