On the effectiveness of uniform suction and injection on unsteady rotating disk flow in porous medium with heat transfer

The unsteady flow of an incompressible viscous fluid above an infinite rotating porous disk in a porous medium is studied with heat transfer. A uniform injection or suction is applied through the surface of the disk. Numerical solution of the nonlinear governing equations which govern the hydrodynamics and energy transfer is obtained. The effect of the porosity of the medium and the suction or injection velocity on the velocity and temperature distributions is considered. (c) 2006 Elsevier B.V. All rights reserved.
