Multiple slip effects on dissipative and chemical reactive MHD flows over a permeable stretching sheet in the presence of heat source

Abstract

The present investigation construes an unsteady MHD flow over a permeable stretching sheet embedded in a porous medium. The effects of viscous and Darcy dissipation, heat source and chemical reaction have been delineated with the existence of multiple slips. Similarity variables are employed for remodeling the governing equations as a system of first order nonlinear ordinary differential equations. The reduced system is numerically solved with 4th order Runge-Kutta method along with shooting technique. The present results have been verified against earlier works and good agreement was found. The important findings reported herein are: porosity acts as aiding factor for the fluid velocity, more dissipative heat leads to higher velocity and temperature, and chemical reaction parameter adversely affects the concentration. This analysis is relevant to various industrial processes at boundaries of pipes, walls, and/or curved surfaces.
