Heat and Mass Transfer of Non-Newtonian Nanofluid Flow Over a Stretching Sheet with Non-Uniform Heat Source and Variable Viscosity

The present article deals with the heat and mass transfer of mixed convection MHD Casson Nanofluid flow over a stretching sheet with variable viscosity and non-uniform heat source. The similarity transformations are utilized for the transformation of partial differential equations to ordinary differential equations. The RK fourth order method based on shooting technique is employed for solving the system. Heat and mass transfer characteristics are performed under the influence of non-uniform heat source and variable viscosity. Impacts of certain emerging parameters on the velocity distribution, temperature field and concentration profiles are studied with the aid of graphs. Numerical results of skin friction factor, local Nusselt and Sherwood numbers for certain values of non-Newtonian fluid parameter, Hartmann number, radiation parameter, Brownian motion parameter, thermophoresis parameter, Schmidt number and Prandtl number are calculated and shown in tabular form. The comparison of our results with the available results is carried out. The out coming result shows nice agreement.
