An Efficient Method for Calculating the Flow Passing Transonic Cascade of Arbitrary Airfoils on a General Surface of Revolution

提出了任意旋成面叶栅跨音速绕流的一种高效率解法。导出了以Ｖｏｎ Ｍｉｓｓｅｓ 坐标为自变量的任意旋成面叶栅中流动的流线控制方程；简单而有效地处理了速度的双 值问题。用数值方法研究了流面半径和流片厚度随轴向变化对于流动的影响。

An efficient method for calculating the transonic flow passing cascade of arbitrary airfoils on a general surface of revolution is presented. Using von Mises coordinates () as the independent variables, a stream line governing equation for the flow on a general surface of revolution is derived and the velocity double value problem is solved simply and efficiently. The effects of the variation in stream surface radius and stream sheet thickness on the flow property was investigated by numerical method.
