Numerical Exploration of MHD Radiative Micropolar Liquid Flow Driven by Stretching Sheet with Primary Slip: A Comparative Study

Abstract

AbstractThe knowledge of thermal transport of magnetohydrodynamic (MHD) flows across a stretching sheet plays a crucial role for transportation, fiber coating, heat exchangers, etc. Due to this fact, we scrutinize the heat transfer features of MHD micropolar fluid flow via a stretching surface in the neighborhood of the stagnation point with Joule heating, by taking advantage of the classical Fourier law. The flow equations are transformed into dimensionless form with the help of suitable similarity transformations. The Runge–Kutta-based shooting method is utilized to solve the converted non-linear coupled equations. Impacts of various physical parameters on the flow fields are represented via graphs. The heat transfer rate, couple stress coefficient and friction factor are presented in a separate table. Results anticipate that fluid temperature is an increasing function of Eckert number, radiation and magnetic parameters, whereas an opposite outcome is noticed for the Prandtl number. It is interesting to notice that the maximum velocity is attained in the absence of slip but maximum temperature is detected in the presence of slip.
