Abstract

The analysis is performed for a mixed convective boundary layer flow in a fluid-saturated porous medium near a vertical surface. In modelling the flow in the porous medium the non-Darcian effects such as the flow inertia, no-slip boundary conditions, nonuniform porosity, and thermal dispersion are taken into account. Because of the porosity variation in the near-wall region, the stagnant thermal conductivity also varies accordingly. These effects have a significant influence on velocity and temperature profiles and heat transfer rate from the flat plate. This work examines these effects on mixed convective transport and demonstrates the variation in heat transfer predictions based on different flow models. The present study also discusses the dependence of fluid flow and heat transfer characteristics on the problem parameters.
