Influence of Thermal Stratification and Variable Viscosity on Non-Darcy Mixed Convective Heat Transfer Past a Porous Wedge in the Presence of Viscous Dissipation

Muhaimin, R. Kandasamy, I. Hashim, Ruhaila


The problem of thermal stratification on non-Darcy mixed convective heat transfer of a viscous and incompressible fluid past a porous wedge in the presence of viscous dissipation is analyzed for the case of variable viscosity. The wall of the wedge is embedded in a uniform non-Darcian porous medium in order to allow for possible fluid wall suction or injection. The governing boundary layer equations are written into a dimensionless form by similarity transformations. The transformed coupled nonlinear ordinary differential equations are solved numerically by using the R.K.Gill and shooting methods. The results are presented graphically and the conclusion is drawn that the flow field and other quantities of physical interest are significantly influenced by these parameters. The results are compared with those known from the literature and excellent agreement between the results is obtained.
