【摘要】 文中采用流函数作为求解变量，推导了离心式压缩机内部回转面上游函数所满足的偏微分方程和定解条件，并运用伽辽金方法建立了相应的有限元方程。对离心式压缩机回转面流场进行了计算，数值计算结果正确地揭示了离心式压缩机内部的流动规律。更多还原

【Abstract】 Taking the stream function as the solution variable,this paper deduces the partial differential equations obeyed by stream function on surface of revolution, establishes corresponding finite element equations by using Galerkin Method. An example is used to verify the method and the program of this paper.The flow on the surface of revolution in a centrifugal compressor is calculated. Numerical results reveal the flow in a centrifugal compressor correctly.更多还原
