A Study on MHD Nanofluid Flow and Heat Transfer with Convective Surface Temperature and Concentration

An analysis has been carried out on MHD nanofluid flow over a stretching sheet embedded in a porous medium taking into account the first order chemical reaction. The uniform heat source/sink and thermal radiation affecting thermal energy distribution in the flow domain under convective heat and mass fluxes are also considered. The highly non-linear partial differential equations are transformed into ordinary differential equations with the help of similarity transformations. Numerical solutions for the governing momentum, energy and concentration equations are given. The physical significance of pertinent parameters on velocity, temperature and concentration as well as skin friction, rate of heat and mass transfer are shown in figures and tables. It is found that the power-law index, Brownian motion and thermophoresis parameters enhance the temperature distribution of the fluid. Higher Schmidt number i.e. heavier diffusing species reduces the solutal boundary layer thickness.
