Numerical solution of micropolar fluid flow via stretchable surface with chemical reaction and melting heat transfer using Keller-Box method

Abstract

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≤M≤3, the range of chemical reaction parameter is 0≤Kr≤1 whereas the values of space-temperature dependent heat source/sink parameters lies in −0.4≤Q≤0.4 and −2≤Q∗≤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.
