Joule Heating and Radiation Absorption Effects on MHD Convective and Chemically Reactive Flow past a Porous Plate

Abstract

The aim of this study is to analyze the effects of Joule heating and radiation absorption on MHD convective and chemically reactive flow past an inclined porous plate in the presence of heat source and thermal diffusion. The non-linear partial differential equations that govern the fluid flow have been transformed into a two-point boundary value problem using similarity variables and then solved numerically by fourth order Runge–Kutta method with shooting technique. Graphical results are discussed for non-dimensional velocity, temperature and concentration profiles while numerical values of the skin friction, Nusselt number and Sherwood number are presented in tabular form for various values of parameters controlling the flow system. The present study is compared with the previous literature and found to be in good agreement. The novelty of this work is the consideration of Ohmic heating, radiation absorption and thermal diffusion.
