The main theme of this research is to find the numerical results of stagnation point flow of micropolar fluid over a porous stretchable surface due to the physical effects of internal heat generation/absorption, melting heat transfer and chemical reaction via Keller-Box method (KBM). The graphs and tables are depicted and explained for various embedded parameters. The range of melting heat transfer parameter is $0\le M\le 3$, the range of chemical reaction parameter is $0\le K_r\le 1$ whereas the values of space-temperature dependent heat source/sink parameters lies in $-0.4\le Q\le 0.4$ and $-2\le Q^{\ast }\le 2$. The upshots of the current problem illustrate that at fluid-solid interface, rate of HMT (heat and mass transfer) declined on escalating the values of stretching parameter. Moreover, as the values of internal heat source/sink parameter increases, heat transfer rate declines at fluid-solid interface.

本研究的主题是通过 Keller-Box 方法 (KBM) 寻找微极流体在多孔可拉伸表面上由于内部发热/吸收、熔化传热和化学反应的物理效应而产生的驻点流动的数值结果. 图表和表格针对各种嵌入式参数进行了描绘和解释。熔化传热参数范围为$0\le 米\le 3$, 化学反应参数范围为 $0\le {钾}_r\le 1$ 而空间温度相关的热源/汇参数的值在于 $-0.4\le 问\le 0.4$ 和 $-2\le {问}^{＊}\le 2$. 当前问题的结果表明，在流固界面，随着拉伸参数值的增加，HMT（传热和传质）速率下降。此外，随着内部热源/汇参数值的增加，流固界面处的传热率下降。
