摘要

摘要: 研究在两个径向伸展的平面之间，微极流体作随时间变化的磁流体动力学（MHD）流动．考虑了高浓度微元（n=0）和低浓度微元（n=0.5）两种情况．使用恰当的变换，将偏微分方程转换为常微分方程．用同伦分析法（HAM），对变换后的方程求解．给出不同参数下，角速度、表面摩擦因数和面应力偶系数的图形结果．

Abstract: This investigation examines the time dependent MHD flow problem of a micropolar fluid between two radially stretching sheets.Both the cases (n=0,0.5) of strong and weak concentrations of microelements are taken into account.Suitable transformations were employed for the conversion of partial differential equations into the ordinary differential equations.The solutions of the resulting problems were developed by a homotopy analysis method (HAM).Angular velocity,skin friction coefficient and wall couple stress coefficient were illustrated for various parameters of interest.
