Sažetak
The unsteady flow of an incompressible viscous fluid above an infinite rotating disk is studied with heat transfer in a porous medium. The disk is started motion impulsively from rest and rotates with a constant angular velocity ω. Numerical solutions of the nonlinear partial differential equations which govern the hydrodynamics and energy transfer are obtained. The effect of the porosity of the medium on the velocity and temperature distributions is considered.
