Impacts of heat and mass flux on MHD flow and heat transfer of radiative nanofluid past an exponentially shrinking/stretching sheet with viscous and Ohmic dissipations
Authors: ,
Abstract: The present correspondence is conveyed to analyze the influence of heat flux and mass flux on magnetohydrodynamic (MHD) and heat transfer flow of radiative nanofluid past an exponentially shrinking/stretching porous sheet with viscous dissipation and Ohmic heating. Heat transfer characteristics with heat generation, thermophoresis, Brownian motion and also chemical reaction effects are addressed. To simulation the equations of momentum, energy and nanoparticle concentration, appropriate similarity transformation variables is employed. These transformed ordinary differential equations are solved numerically using the Nachtsheim-Swigert shooting technique scheme together with fourth order Runge-Kutta method. The effects of several parameters on the dimensionless velocity, temperature and concentration profiles are presented graphically. This study discloses that the variable heat and mass fluxes have important impacts on the temperature profile and concentration. We have found that solutions exist in both shrinking and stretching cases. It is remarked that the presence of radiation, Brownian motion, heat generation and magnetic interaction parameter enhances the temperature and reduces the concentration profile
