Heat generation effects on Magnetohydrodynamic Powell-Eyring fluid flow along a vertical surface with a Chemical reaction

Abstract

This work examines the influence of double diffusion on MHD Powell-Eyring fluid flow with free convection through a vertical surface. In addition, the impacts of chemical reaction, heat generation, local magnetic field, Grashof number and local modified Grashof number parameters are considered. The analysis of double diffusive in the occurrence of fluid flow under the convective surface conditions is studied. To translate the governing PDEs of velocity, energy and species (solutal) concentration equation, a couple of nonlinear ODEs we relate the suitable transformation of similarity. The set of nonlinear ODE's numerically and attained numerical consequences are connected by those gained through the assistance of MATLAB procedure bvp4c. The impact of prominent constraints of chemical reaction, Prandtl number, Schmidt number, heat source parameter, magneto hydrodynamic parameter, on dimension less velocity, energy and solutal (species) concentration dissemination has been considered. Impacts of different parameters such as skin friction coefficient, Nusselt number and Sherwood number are described through tables.
