Heat and mass transfer of a second grade magnetohydrodynamic fluid over a convectively heated stretching sheet

•Effect of thermal radiation on second grade fluid in the presence of thermophoresis is studied.•The rate of mass transfer increases with the increase of thermophoretic parameter.•The rate of heat transfer increases for increasing the values of the surface convection parameter.•The temperature profile enhances with increase in the thermal radiation parameter.

The present work is concerned with heat and mass transfer of an electrically conducting second grade MHD fluid past a semi-infinite stretching sheet with convective surface heat flux. The analysis accounts for thermophoresis and thermal radiation. A similarity transformations is used to reduce the governing equations into a dimensionless form. The local similarity equations are derived and solved using Nachtsheim-Swigert shooting iteration technique together with Runge-Kutta sixth order integration scheme. Results for various flow characteristics are presented through graphs and tables delineating the effect of various parameters characterizing the flow. Our analysis explores that the rate of heat transfer enhances with increasing the values of the surface convection parameter. Also the fluid velocity and temperature in the boundary layer region rise significantly for increasing the values of thermal radiation parameter.
