摘要
不可压缩粘性流体,流过可移动、温度交变振荡的半无限垂直圆柱体时,对MHD自由对流影响的数值解进行了研究.应用Crank-Nicolson型的隐式有限差分方法,求解无量纲、不稳定、非线性、耦合的偏微分控制方程.在不同参数下研究速度、温度和浓度分布的变化,还分析了局部及平均的表面摩擦力、Nusselt数和Sherwood数,并以图形形式给出.所得结果与其他文献的结果比较,有着很好的一致性.
Numerical solutions of MHD effects on free convective flow an incompressible viscous fluid past a moving semi-infinite vertical cylinder with temperature oscillation was presented. The dimensionless, unsteady, non-linear and coupled governing partial differential equations were solved using an implicit finite difference method of Crank-Nicolson type. The velocity, temperature and concentration profiles were studied for various parameters. The local as well as average skin-friction, Nnsselt number and Sherwood number were also analyzed and presented graphically. The present results are compared with available results in literature and are found to be in good agreement.
