Characteristics of heat transportation in MHD flow of chemical reactive micropolar nanofluid with moving slip conditions across stagnation points

Abstract

In current study, the steady electrically conducting flow of micropolar nanofluid past a porous stretched surface across stagnation points is investigated. For motivation of problem, the impressions of the nonlinear thermal radiation and convectively heated have been analyzed. In additions, the influence of thermophoresis and heat transfer are the part of this study. The governing firm of PDEs are converted to a system of nonlinear and coupled ODEs using the similarity approach. Moreover, the resulting problem is numerically integrated with the aid of shooting approach by utilizing the bvp4c programmer of MATLAB. The numerical outcomes are calculated using various physical parameter values and contrasted with previously published results. Numerical values of the physical quantities like velocity, micropolar rotation, temperature and concentration profile for involving parameters such as Prandtl number Pr, radiation R, slip parameter α, thermophoresis Nt, suction/injection velocity fw, Brownian motion Nb, magnetic parameter M and Lewis number Le are also computed and deliberated in this consideration.
