Mixed convection heat transfer to modified second grade fluid in the presence of thermal radiation

The aim of the current research is to contemplate the mixed convection flow and heat transfer of the modified second grade fluid by examining the thermal radiation effects in the presence of the convective boundary conditions. The boundary layer phenomenon is adopted for the flow past a non-linearly stretching surface in consideration of assisting and opposing buoyancy effects. The reduced governing ordinary differential equations obtained by using appropriate local similarity transformations are numerically integrated by the help of shooting method. The impact of various emerging parameters on the velocity and temperature fields is graphically displayed for assisting as well as opposing flows. It is inferred that the skin friction coefficient and the heat transfer rate at the wall reduces with the progressive values of the generalized Biot number and the thermal radiation parameter.
