用同伦分析方法求解具有抽吸喷注的运动延伸表面上流动问题

On the homotopy analysis method for solving the boundary layer flow problem over a stretching surface with suction and injection

研究了具有抽吸喷注的多孔介质延伸表面上二维稳态层流的流动问题.用一种解析的方法——同伦分析方法——求得了该流动问题的相似解.给出了量纲为一的速度分布以及在不同渗透参数情况下壁摩擦系数的变化.

This paper studied two-dimensional steady laminar flow over a porous medium stretching surface with suction or injection. The homotopy analysis method, a kind of analytical method, was applied to solve the problem. The solution presents representative profiles for the dimensionless velocity and the skin friction coefficient at different permeability and injection parameters.
