Abstract: 

This paper focuses on the effect of thermal radiation on unsteady free convection viscous incompressible clectrically conducting fluid with dissipative heat between two long vertical plates when the temperature of one of the plates oscillates about a constant non zero mean temperature. The governing equations are solved by regular perturbation technique. The expressions for the velocity field, temperature field, the skin friction at the plate and Nusselt number are obtained in non-dimensional forms. Computations are performed for a wide range of the governing flow parameters, viz., the Hartmann number, Grashof Number for heat transfer, Prandtl Number and Radiation parameter. The effects of these flow parameters on the velocity, temperature, skin friction and Nusselt number are presented graphically and results are discussed.
