Free convection Effects on the oscillatory Flow Past a vertical Porous Plate in the presence of Radiation for an Optically thin Fluid

We study the three dimensional free convective oscillatory flow and mass transfer of viscous and optically thin gray fluid over a porous vertical plate with transverse sinusoidal suction in the presence of radiation. The governing partial differential equations have been transformed to ordinary differential equations. Numerical solutions are obtained for different values of radiation parameter, Grashof number and Schmidt number.
