非牛顿二阶流体的运动方程是一个高维的非线性微分方程,其精确解求解非常困难.本文利用逆方法求得非牛顿流体在多孔介质和霍尔电流效应下的几类精确解,所得的精确解有助于人们认识和理解非牛顿流体的流动特性.
The equations of non-Newtonian second-grade fluid flow are highly nonlinear partial differential equations. This paper aims to investigate analytical solutions of non-Newtonian fluid for porous medium channel and Hall current effects via inverse method for steady and unsteady cases. The exact solutions help us to understand the flow characteristics of non-Newtonian fluids.
