摘要

Film cooling efficiency of rotating turbine blades with compound angle holes has been investigated by numerical simulation. Calculations of moving blades under different rotational speed. The effect of rotational speed. blowing rate and incidence angle of the cooling air jet at leading edge on film cooling have been analyzed. Calculation results show that rotation blade film cooling jet skew to blade tip. Cooling effect on the both pressure and surface surface to drop the quicker the rotation, the lower the cooling effect.
