Magnetohydrodynamic Heat and Mass Transfer of Sisko Nanofluid Past a Stretching Sheet with Nonlinear Thermal Radiation and Convective Boundary Condition

This paper is concerned with the study of nonlinear thermal radiation and uniform magnetic field on heat and mass transfer of Sisko nonofluid over a stretching sheet with convective boundary condition. The highly nonlinear governing partial differential equations of Sisko nonofluid boundary layer flow are transformed first into coupled nonlinear ordinary differential equations using similarity transformations and then the resulting boundary layer equations are solved numerically using fifth order Runge-Kutta-Fehlberg method with schooting technique. The influence of Sisko fluid, power-law index, thermal radiation, magnetic field, Brownian motion, thermophoresis parameters and Biot number on velocity, temperature and concentration fields as well as on the skin-friction coefficient, local Nusselt number and local Sherwood number are well illustrated graphically to establish some important physical phenomena. It is found that temperature distribution decreases with increasing the values of the Sisko fluid parameter, whereas it increases with Biot number gamma.
