MHD Stagnation Point Flow Towards a Heated Shrinking Surface Subject to Heat Generation/Absorption

摘要

摘要: 分析了微极流体朝向加热伸展平面的磁流体动力学（MHD）驻点流动，考虑了粘性耗散和内部产热/吸热对流动的影响．讨论了指定表面温度（PST）和指定热通量（PHF）两种情况，采用同伦分析方法（HAM）求解边界层流动和能量方程．通过图表的显示，研究了感兴趣物理量的变化．注意到高伸展参数时解的存在与外加应用磁场密切相关．

Abstract: The magnetohydrodynamic (MHD) stagnation point flow of micropolar fluid towards a heated shrinking surface was analyzed. The effects of viscous dissipation and internal heat generation/absorption were taken into account. Two explicit cases of prescribed surface temperature (PST) and prescribed heat flux (PHF) were discussed. The boundary layer flow and energy equations were solved by employing a homotopy analysis method (HAM). The quantities of physical interest were examined through the presentation of plots/tabulated values. It was noticed that existing of solution for high shrinking parameter was associated closely with the applied magnetic filed.
