ABSTRACT

In this work slip velocity effects on convection from a vertical plate embedded in saturated porous medium using the Darcy model are investigated numerically. The governing equations − continuity, Darcy law, and energy − are transformed into dimensionless form using a suitable set of dimensionless variables. The equations are solved numerically using a finite-difference method. Results obtained are shown graphically interdicted to illustrate the effects of slip velocity on the near-plate fluid velocity, temperature, shear stress, and Nusselt number. It was found that the increasing of slip velocity decreases velocity and increases heat transfer rates near the surface.
