摘要

摘要: 研究有抽吸作用的可收缩薄片上的磁流体动力学粘性流动．讨论了二维轴对称可收缩问题．利用相似变换给出了无量纲形式的边界层控制方程．利用现代数值技术，数值地求解变换后耦合的非线性常微分方程组，并与现有文献的结果进行了比较．得到了无量纲速度、温度、浓度的分布，以及表面摩擦、传热率、传质率和沉积率的数值结果，并用图形显示了与解有关的重要参数．

Abstract: The magnetohydrodynamic viscous flow due to a shrinking sheet in the presence of suction is concerned with.The cases of two dimensional and axisymmetric shrinking were discussed.The governing boundary layer equations were written into a dimensionless form by similarity transformations.The transformed coupled nonlinear ordinary differential equations were solved numerically by using the advanced numeric technique.Favorable comparison with previously published work was performed.Numerical results for the dimensionless velocity,temperature and concentration profiles as well as for the skin friction,heat and mass transfer and deposition rate were obtained and displayed graphically for pertinent parameters to show interesting aspects of the solution.
