多孔介质中非线性延伸壁面上驻点流动的非相似解
Non-similarity solutions of stagnation-point flow over a nonlinear stretching sheet embedded in a porous medium
摘要
Abstract
The stagnation-point flow towards a nonlinear stretching sheet based on incompressible viscous flow had been mainly investigated, considering the effects of the porosity and permeability of a porous medium. Introducing the dimensionless transformations, the governing equations describing the stagnation point flow were reduced and solved by homotopy analysis method, which was introduced to obtain the non-similarity solutions of the governing equations. The influences of the important parame-ters including porosity, permeability and nonlinear parameter on the skin friction coefficient and veloc-ity profile were discussed in detail. The results showed that the impact of porosity and nonlinear param-eter were larger than the permeability on velocity profile.关键词
