Abstract:

The combined effects of hall current, thermal radiation on an unsteady MHD free convection casson fluid flow of a viscous, incompressible and electrically conducting fluid past an infinite vertical plate are investigated in presence of heat transfer. Numerical solutions of the non-linear coupled governing equations is obtained by finite element technique. The expressions for primary fluid velocity, secondary fluid velocity and fluid temperature, skin friction due to primary and secondary velocity fields and rate of heat transfer coefficient due to temperature at the plate are obtained and discussed with the help of different material parameters like Grashof number for heat transfer, Casson fluid parameter, Magnetic field parameter, hall parameter, thermal radiation parameter, Prandtl number. Finally, it is seen that the numerical results of the present study conform very well to those of previous studies reported in available scientific literatures.
