MIXED CONVECTION FLOW OF A VISCOELASTIC FLUID THROUGH A POROUS MEDIUM IN A VERTICAL CHANNEL WITH PERMEABLE WALLS

Abstract

 In this paper, we investigated the fully developed mixed convection flow of a viscoelastic fluid through a porous medium in a vertical channel with permeable walls. The governing non – linear equations are solved for the velocity field and temperature field using the traditional perturbation technique. The effects of viscoelastic parameter Reynolds number, Grashof number, cross flow parameter  and Prandtl number  temperature on the velocity and temperature are discussed in detail with the help of graphs.
