It is found in the experiments that film hole reynolds number and rib angle have great influence on film hole discharge coefficients 实验中发现气膜孔雷诺数和肋角对流量系数有较大的影响。
2.
Film hole discharge coefficients at first increase with the increase of film hole reynolds number and then keep almost constant when film hole reynolds number exceeds 15000 流量系数随气膜孔雷诺数的增大而增大,当雷诺数达到15000以后,流量系数随雷诺数的变化变小。
