ABSTRACT

The forced-convection boundary-layer slip flow and heat transfer of an incompressible viscous fluid over a permeable plate (with suction) embedded in a Darcy porous medium is investigated. At the plate surface the velocity and thermal slip conditions are taken into consideration. The conservation equations are transformed by the similarity technique to two nonlinear ordinary differential equations (ODEs) and then solved using the semianalytical Adomian decomposition method (ADM)−Pade approximants. The results reveal that the dimensionless fluid velocity gradient at the plate surface decreases with increase in the velocity slip parameter. However, the dimensionless fluid velocity at the plate surface increases with the velocity slip parameter. Moreover, the local skin friction coefficient decreases with increase in the velocity slip parameter.
