SLIP EFFECTS ON BOUNDARY LAYER FLOW AND MASS TRANSFER WITH CHEMICAL REACTION OVER A PERMEABLE FLAT PLATE IN A POROUS MEDIUM

摘要

A mathematical model is presented to analyse the steady boundary layer slip flow and mass transfer with nth order chemical reaction past a porous plate embedded in a Darcy porous medium. Velocity as well as mass slips are considered at the boundary. The governing PDEs are transformed into self-similar nonlinear ODEs by similarity transformations. The reduced nonlinear equations are solved numerically. The momentum boundary layer thickness is reduced for increase of permeability and suction parameters, whereas it increases with blowing parameter. The increase of velocity slip parameter reduces the momentum boundary layer thickness and also enhances the mass transfer from the plate. Importantly, due to increase of mass slip the concentration and mass transfer decrease.
