Viscous dissipation and Joule heating effects on MHD flow of a Thermo-Solutal stratified nanofluid over an exponentially stretching sheet with radiation and heat generation/absorption

The present study is focused on the influence of viscous and joules dissipation on magnetohydrodynamic flow of a double-stratified nanofluid past an exponentially stretching sheet in the presence of thermal radiation and heat generation/absorption effects. The governing nonlinear partial differential equations are transformed into a system of nonlinear ordinary differential equations using similarity variables and then solved numerically for these equations is procured by employing the Nachtsheim-Swigert shooting technique scheme together with Runge-Kutta Fourth-Order method. A parametric analysis has been carried out to investigate the impacts of physical parameters taken in the problem. The pattern worked for the nanofluid transport equations unified the impacts of thermophoresis and Brownian motion. Numerical results are obtained for the velocity, temperature and concentration in the boundary layer region is studied in elaborate. The impact of physical interest such as local skin friction coefficient, local nusselt number, and local Sherwood number are also investigated numerically and are tabulated. It is remarked that Schmidt number and thermal stratification parameter decreases the dimensionless temperature, during the solutal stratification parameter decreases the dimensionless concentration.
