| 摘 要： | 本文提出一种解叶栅绕流反问题的近似方法.利用假想气体近似,将可压缩流动平面的反问题,变换为虚拟的不可压流动平面上的反问题.采用边界元方法造代求解出叶片型线,然后再变换到原物理平面.本文还对亚音速、无激波跨音速叶栅的三个例子作了数值计算.

| Abstract: | An approximate method for solving the inverse problem in two-dimensional
compressible cascade flow is suggested by the authors.With the fictitious gas approach,the
inverse problem of compressible flow in a cascade may be transformed into the inverse
problem of incompressible flow in a mapped cascade.Adopting the boundary element
method,the blade profile is gained iteratively,and then transformed back to the original
physical plane.Three samples in subsonic and transonic regimes are also computed
respcctively. |
