Abstract

We study the heat transfer of a Magneto Hydrodynamic (MHD) boundary layer flow of a Newtonian fluid over a pervious shrinking sheet under the influence of thermal slip. The flow allows electric current to pass through. The governing PDEs are transformed into self-similar ODEs via Lie group analysis. We study the variations in the dimensionless quantities like velocity and temperature of the flow in terms of the different parameters involved in the problem. We discuss the thickness of the boundary layers under the influence of various parameters involved in the flow. Numerical simulations are carried out to explain and support the results obtained.

摘要

我们研究了在热滑移影响下,牛顿流体在可渗透收缩薄板上的磁流体动力学(MHD)边界层流动的传热问题。该流动允许电流通过。通过李群分析将控制偏微分方程转化为自相似常微分方程。我们根据问题中涉及的不同参数,研究了流动的无量纲量(如速度和温度)的变化。我们讨论了流动中各种参数影响下边界层的厚度。进行了数值模拟以解释和支持所获得的结果。
