摘要
本文采用边界元法求解三维无粘不可压流动问题。通过详细的数学推导,得到了三维边界元法在区域边界上数值离散后的代数方程,并以此方程编制了计算机程序。三维管道的计算结果表明,本文的尝试是成功的。用边界元法求解叶轮机内三维流动问题是一种现实可行的新方法。
In this paper, a boundary element method is presented to sclve the three-dimensional invisdd incompressible flow. After a discretizafion on the boundary of a computational domain, the general 3-D boundary element equations are defiveted in detail. with that, a computational program for 3-D inviscid incompressible flow in cascade canal is compile. The calculation result show that the attempt in this paper is successful, and the new method of by use that to solve 3-D flow in turbomachine is reality and feasible.
