通过改变气膜孔出口槽的位置和形状,在吹风比M=0.5、M=1.0和M=1.5的条件下,对5种不同结构的气膜孔平均冷却效率进行了数值模拟研究,结果表明横向槽能够显著地提高气膜孔的平均冷却效率。
It investigated the average cooling effectiveness of five film cooling structure with transverse slots at different blowing ratio M=0.5,M=1.0 and M=1.5. It can be concluded that the transverse slot can improve the average cooling effectiveness obviously.
