摘要
对五孔单排锥形孔气膜冷却进行了实验研究,测出了孔排下游的局部换热系数及冷却效率,并研究了喷气雷诺数及吹风比的影响。实验参数范围是:喷气雷诺数Re=10000~25000,吹风比M=0.3~2.0,测量分26个工况进行。
Film cooling of a row of five coneshaped holes has been studied experimentallyLocal heat transfer coefficients and film cooling effectiveness of downstream of hole row were measured and the influences of coolant Reynolds number and blowing rate are describedThe ranges of these parameters are:the coolant Reynolds number from 10000 to 25000 and blowing rate from 03 to 20 Measures were performed for 26 conditions
