摘　　要：在两个具有热交换可渗透的多孔圆盘之间,研究三阶流体的磁流体动力学(MHD)流动.通过适当变换,将偏微分的控制方程转换为常微分方程.采用同伦分析法(HAM)求解转换后的方程.定义了均方残余误差的表达式,并选择了最佳的、收敛的控制参数值.检测了无量纲参数变化时的无量纲速度和温度场.列表显示表面摩擦因数和Nusselt数,并分析了无量纲参数的影响.The magnetohydrodynamic（MHD） flow of third-grade fluid between two permeable disks with heat transfer was investigated.The governing partial differential equations were converted into the ordinary differential equations by using suitable transformations.Transformed equations were solved by using homotopy analysis method（HAM）.The expressions for square residual errors were defined and optimal values of convergencecontrol parameters were selected.The dimensionless velocity and temperature fields were examined for various dimensionless parameters.Skin friction coefficient and Nusselt number were tabulated to analyze the effects of dimensionless parameters.
