The test Reynolds number based on the incoming flow and the bladechord was 100000. The measured results were analyzed in conjunction with the flow fields mapped by using five hole probe.
并结合以前通过五孔针测量取得的流场进行了分析， 得出了该叶栅中紊流参数的变化规律。

Other causes include the out - of - tolerance of bladechord width between adjacent blades, the undersize contact area of serrated working side and the local wearing of non - working side.
而相邻原机件叶片弦宽尺寸超差，锯齿形工作接触面积小，以及非工作面局部碰磨，是引发故障的次要因素。

The influences of re based on the bladechord length and coolant-gas flux ratio are tested, and comparison is made between the effect of the converging-expanding hole rows and cylindrical hole rows.
