选定三种厚薄叶片间置叶排设计安装方案,在平面叶栅试验器上进行试验研究。试验结果表明,就单个叶片而言,厚叶片和薄叶片相比,临界M数由0.722降低到0.685,损失系数由0.0084增加到0.0284;就叶栅中间五个叶片槽道的平均性能而言,改进方案B和原方案A相比,性能有明显改善,临界M数由0.69增加到0.707,损失系数由0.0169降低到0.0135。 The design and installation plan of three kinds of thick-leaf inter-row leaves are selected and tested on the plane-leaf cascade tester. The experimental results show that for a single blade, the critical M number decreases from 0.722 to 0.685 and the loss coefficient increases from 0.0084 to 0.0284 compared with the thin blade. For the average performance of the five blade channels in the middle of the cascade, Compared with the original scheme A, the improved scheme B has obviously improved its performance, the critical M number increased from 0.69 to 0.707, and the loss coefficient decreased from 0.0169 to 0.0135.
