suction side of runner blade 转轮叶片背面
The cooling effectiveness of pressure side of blade was higher than suction side.
层板叶片压力面的冷效略高于吸力面。
The results show that the cooling effectiveness on concave side is better than suction side with laying film cooling holes in concave side at leading edges of turbine blade.
结果表明，叶片前缘压力面侧布置的气膜孔对叶片压力面有很好的冷却效果；
