Combined convection in power-law fluids along a nonisothermal vertical plate in a porous medium

Abstract

The problem of combined convection from vertical surfaces in a porous medium saturated with a power-law type non-Newtonian fluid is investigated. The transformed conservation laws are solved numerically for the case of variable surface heat flux conditions. Results for the details of the velocity and temperature fields as well as the Nusselt number have been presented. The viscosity index ranged from 0.5 to 2.0.

Influence of Dufour/Soret and Space-Dependent Internal Heat Source on Combined Convection of Non-Newtonian Fluids Flow Past a Vertical Full Cone in Porous Media: The VHF/VMF Case

“…In the aspect of free convection, Mehta and Rao (1994) studied buoyancy-induced flow of non-Newtonian fluids in a porous medium past a vertical flat plate with nonuniform surface heat flux. Combined convection in power-law fluids along a nonisothermal vertical plate in a porous medium was examined by Kumari and Gorla (1996). Yang and Wang (1996) solved free convection heat transfer of non-Newtonian fluid over axisymmetric and two-dimensional bodies of arbitrary shape embedded in a fluid-saturated porous medium.…”
