Time varying rotating disk flow with heat transfer of a non-Newtonian fluid in porous medium

Abstract

Time varying flow through a porous medium of an incompressible viscous non-Newtonian fluid due to a rotation of an infinite rotating disk is studied with heat transfer. Numerical solutions using finite differences are obtained for the nonlinear partial differential equations which govern the hydrodynamics and energy transfer. The effect of the porosity of the medium and the characteristics of the non-Newtonian fluid on the velocity and temperature distributions is considered.
