Abstract

In this paper, we study the behavior of heat transfer of Casson fluid at the magnetohydrodynamic stagnation point with thermal radiation over a continuous moving sheet. The appropriate similarity transfer is used to transfer the governing differential equations into the ordinary differential equation and then solved by the collocation method based on spline function. The obtained results are investigated with the existing literature by direct comparison. We found that an increment in the value of the shrinking parameter, magnetic parameter, and Casson fluid parameter enhances the velocity distribution and depreciate the temperature profile both Casson and Newtonian fluids. Furthermore, the thermal distribution depreciates with increasing the value of Prandtl number and radiation parameter for Casson and Newtonian fluids. Finally, the impact of the emerged physical parameters on the velocity and temperature distributions are illustrated via tables and illustrative graphs.
