Opposite Behavior

Mathematical modeling to study the effect of nonlinear thermal radiation on Casson nanofluid flow between parallel plates is established. Second order velocity slip condition is implemented at the boundary of the lower plate. An appropriate transformation is applied to alter the PDEs into ODEs and then tackled numerically by employing RKF-45. The consequence of several prevailed parameters on the Casson nanoliquid velocity components, temperature and concentration fields are portrayed graphically and deliberated in detail. Velocity component decreases near the region of lower plate while it increases along the upper plate region for magnetic and slip parameter whereas opposite behavior is obtained for the Casson parameter for the same component.
