摘要

本文从热辐射和粘性耗散的影响出发,研究了导电流体在具有均匀质量扩散和均匀温度的垂直位置振荡半无界板上的流动。采用一种有效且无条件稳定的隐式有限差分方法,即Crank-Nicolson方法来求解无量纲控制方程。根据数值结果,分析了不同物理参数值对浓度、温度的影响;速度;舍伍德数、努塞尔数和皮肤摩擦曲线以图形形式显示,并对其结果进行了彻底的分析。我们观察到,当磁场、辐射和相角参数增大时,速度减小。这表明,平板振荡、辐射和磁场对流型有显著影响。

Numerical study of a transient MHD flow across an oscillating vertical plate with thermal radiation and viscous dissipation
The flow of an electrically conducting fluid across a vertically positioned oscillating semi-boundless plate with uniform mass diffusion and temperature is examined in this study in terms of the effects of thermal radiation and viscous dissipation. The dimensionless governing equations were solved using an effective and unconditionally stable implicit finite-difference approach known as the Crank-Nicolson method. Based on the numerical results, the impacts of various physical parameter values on concentration, temperature; velocity; Sherwood numbers, Nusselt numbers and skin-friction profiles are displayed graphically and their consequences thoroughly analyzed. We observed that when the magnetic field, radiation and phase angle parameters are increased, the velocity is reduced. This shows that plate oscillation, radiation and magnetic fields affect the flow pattern significantly.
