摘要

在本研究中，我们考虑了两个多孔板之间的卡森流体在传热和磁效应存在下的渗透率准则。一组适当的相似变换将Navier-Stokes方程简化为具有边界条件的非线性方程。同伦摄动法是一种高效、稳定的求解方法。并将所得结果与有效的有限差分法计算结果进行了比较。本分析的目的是研究该问题中出现的四种不同情况，即吸力、注射、混合吸力和混合注射，以及磁效应和传热特性。利用所得结果分析了流体的速度和温度分布，并以图形和表格的形式显示了两种方法在上下板处的表面摩擦。所得的半解析解与数值解吻合较好。

HEAT TRANSFER ANALYSIS OF MHD CASSON FLUID FLOW BETWEEN TWO POROUS PLATES WITH DIFFERENT PERMEABILITY

In the present study, we consider Casson fluid flow between two porous plates with permeability criteria in the presence of heat transfer and magnetic effect. A proper set of similarity transformations simplify the Navier-Stokes equations to non-linear ODEs with boundary conditions. The homotopy perturbation method is an efficient and stable method which is used to get solutions. Further, the results obtained are compared with the solution computed through an effective and efficient finite difference approach. The purpose of this analysis is to study the four different cases arise viz: suction, injection, mixed suction and mixed injection in this problem, along with magnetic effect and heat transfer characteristics. The results obtained are used to analyse the fluid velocity and temperature profiles, and the skin friction at the upper and lower plate by using both methods are displayed in the form of figures and tables. The semi-analytical solution obtained is in good agreement with the numerical solution.
