The effects of thermal radiation on the flow of a viscous incompressible fluid occupying a semi-infinite region of space bounded by an infinite horizontal moving hot plate in the presence of indirect natural convection by way of an induced pressure gradient, is considered. The fluid is a gray, absorbing-emitting radiation but a nonseattering medium. An exact solution is obtained for the flow by applying the Laplace transform technique. The numerical results of velocity distributions are depicted graphically for different values of radiation parameter K1 and Grashof number Gr, taking the Prandtl number Pr=0.71 and t=0.2 are kept fixed. It is observed that the velocity slightly decreases with increasing the value of radiation parameter while the velocity is slightly decreases with an increase in Gr whereas there exists a reverse flow on increasing Gr due to the presence of the induced pressure gradient.
