摘要

摘要: 在横向磁场作用下，不可压缩的粘性导电流体，流经一个半无限的竖板，完成了壁面温度变化对磁流体动力学流动的分析．假定由粘性耗散和感应磁场产生的热量可以忽略不计．无量纲的控制方程为二维非稳态耦合的非线性方程．结果显示，磁场参数对空气和水的速度有着抑制作用．

Abstract: An analysis was performed to study them agneto hydrodynamic flow of an electrically conducting, viscous incompressible fluid past a semi-infinite vertical plate with variable surface temperature, under the action of transversely applied magnetic field was carried out. The heat due to viscous dissipation and the induced magnetic field were assumed to be negligible. The dimension less governing equations are unsteady, two-dimensional, coupled and non-linear governing equations. It is found that the magnetic field parameter has a retarding effect on the velocity of air and water.
