【Abstract】 In this article, supposing that the fluid is invisid incompressible and potential. The authors analyze and calculate partial cavitation flow around two-dimensional straight-linecascade by using surface-singularity method and nolinear theory.So the shape of cavity and the distribution of pressure and velocity on blade surfaCe are obtained. In this paper, the calculating formula of partial cavitation flow in axial-flow hydraulic machinery are given.By calcalation the cavitation range and maximum thickness of cavity and it’s position can be determined.更多还原
