含沙水流定常边界层的流动特性研究

Namerical computation of boundary layer in stationary silt-laden two-phase flow

本文在推导固液两相流动边界层数学模型的基础上 ,采用泊松 (Poisson)方程来生成网格 ,使网格的生成得到较好的控制 ,同时对方程进行适体坐标变换并利用有限差分法对之进行离散求解。

On the base of the mathematical model of boundary layer in two phase flow,it is better to generate grids by Poisson equation.BFC transformation and infinite difference are used for the solution of boundary flow,it's a practical method for flow field calculation of two phase flow.
