Abstract

Abstract : The Darcy-Brinkman free convection near a wedge and a cone in a porous medium with high porosity has been considered. The surfaces are subjected to a mixed thermal boundary condition characterized by a parameterm ;m = 0, 1, ∞ correspond to the cases of prescribed temperature, prescribed heat flux and prescribed heat transfer coefficient respectively. It is shown that the solutions for differentm are dependent and a transformation group has been found, through which one can get solution for anym provided solution for a particular value ofm is known. The effects of Darcy number on skin friction and rate of heat transfer are analyzed.
