Abstract: In this paper, we have investigated the effects of radiation on unsteady magneto-hydrodynamic (MHD) fluid flow past an impulsively started infinite isothermal vertical plate taking into account viscous dissipation. The fluid is considered a gray, absorbing-emitting radiation but non-scattering medium. The dimensionless boundary layer equations of the flow are solved subject to boundary conditions using the Ritz FEM. The obtained numerical results for velocity and skin-friction are presented through the graphs and tables. It has been found that an increase in the radiation parameter decreases the fluid velocity and with increasing Eckert number and Grashof number increases the fluid velocity. The skin-friction increases with increase in the radiation parameter and decreases with increase in the Grashof number and time parameter
