摘要：
This study is aimed at researching surface roughness effect on the performance of blades in terms of aerodynamics Numerical simulation on a rough flat plate with a row of 35 round film holes under different roughness heights, Reynolds numbers and blowing ratios is conducted to see how they affect film cooling on a flat plate. In terms of aerodynamics, the increase of surface roughness height, Reynolds number and blow ratio will result in the increase of skin friction coefficient. Besides, roughness has combined effects with Reynolds number and blowing ratio So the effect of surface roughness on blades' performance is too big to ignore.
