| 摘 要： | 分析了化学反应，对流过半无限竖直多孔板的、粘性耗散的、非定常的磁流体流动的影响．利用随时间变化的相似参数，将运动、能量、溶质的控制方程变换为常微分方程，并用有限单元法数值地求解所得到的常微分方程．用图形给出了不同参数对速度、温度和浓度分布的影响，用表格给出了不同物理参数值时，表面摩擦力、Nusselt数和Sherwood数的数值．

| Abstract: | A chemical reaction effect on an unsteady magnetohydrodynamic flow past a semi-infinite vertical porous plate with viscous dissipation was analyzed.The governing equations of motion,energy and species were transformed into ordinary differential equations using time dependent similarity parameter.The resultant ordinary differential equations were then solved numerically by a finite element method.The effects of the various parameters on the velocity,temperature and concentration profiles were presented graph... |
