摘要
在低展弦比矩形透平静叶栅中，占总损失主要部分的二次流损失与出口截面上通道涡的位置和尺度有关．本文通过在较大冲角范围内对具有不同倾斜角叶片叶栅出口流场的测量，研究旋涡结构与二次流的关系，从而进一步完善降低二次流损失的方法．
In turbine rectangular cascades with small aspects the secondary flow losses which possess the main proportion of overall losses depend on positions and dimensions of the passage vortices.By measurement of outlet flow fields, the relations between outlet flow vortex compositions and secondary flow losses were studied, and the effective approach of reducing secondary flow losses by applaying leaned blades is suitable in the case of incidences as well.
