【摘要】 <正> 一、前言 近年来叶轮机械的研究主要是正问题的内容。其中尤以粘性、跨音定常流进展较为迅速。反问题的研究只有在最近一些年来,由于叶轮机械的设计实践需要才得以迅速的发展。如流、势函数法解决了无旋方程的反问题求解。文献[2]提出了流函数有旋方程的直接反问题形式的数学模型,在文献[3,4]的基础上推导出了以计算网格的曲线坐标为独立变量的反问题控制方程组。本文研究了考虑粘性作用的S₁反问题的计算方法,用分更多还原

【Abstract】 A alternative iterative method solving the viscous inverse problem in transonic flow conditions is successfully developed. The viscous stream function equation is deduced. The advantage of this method is that the prescribed velocity and thickness distribution can be got therefore the excellent gas dynamic performance and the satisfactory strength performance can be obtained. While the loss of profile can be calculated and the flow separation can be controled. The calculated results of examples show that this method is reasonable and satisfactory.更多还原
