In the present paper, we study the magnetohydrodynamic stagnation point flow dealing with heat and mass transfer of a micropolar nanofluid influenced with heat generation and viscous dissipation. Nonlinear ordinary differential equations are obtained by applying suitable similarity transformation on the governing partial differential equations. These differential equations have been solved by successive linearization method (SLM). The effects of various dimensionless parameters, such as heat generation parameter, thermophoretic parameter and stagnation parameter on the flow field, are discussed through tables and graphs by accumulating sufficient data using SLM. Results show many important facts, including temperature distribution gradual increment with the increase of heat generation and microrotation parameters. Quadratic multiple regression analysis has been performed for skin friction coefficient, local Sherwood number and local Nusselt number. When free stream velocity and stretching velocity are equal, variation in microrotation and magnetic field leads to very low perturbation in skin friction, local Sherwood number and local Nusselt number, whereas when free stream velocity is dominant over stretching velocity, there occurs reverse heat flow at the surface of the sheet.

在本文中，我们研究了磁流体动力学停滞点流动，该流动涉及受热产生和粘性耗散影响的微极性纳米流体的传热和传质。非线性常微分方程是通过在支配的偏微分方程上应用适当的相似变换而获得的。这些微分方程已通过连续线性化方法（SLM）求解。通过使用SLM积累足够的数据，通过表格和图表讨论了各种无因次参数，例如生热参数，热泳参数和停滞参数对流场的影响。结果表明许多重要事实，包括随着热量的产生和微旋转参数的增加，温度分布逐渐增加。对皮肤摩擦系数，局部Sherwood数和局部Nusselt数进行了二次多元回归分析。当自由流速度和拉伸速度相等时，微旋转和磁场的变化导致皮肤摩擦，局部舍伍德数和局部纳塞尔特数的扰动非常低，而当自由流速度超过拉伸速度时，在纸的表面。
