HEAT AND MASS-TRANSFER FLOWPAST A VERTICAL POROUSWALL WITH VARIABLE HEAT AND MASS FLUX

ABSTRACT

The present paper deals with an analysis of mixed convection heat and mass-transfer flow of an incompressible, viscous fluid along an infinite porous vertical wall embedded in a homogeneous porous medium with variable suction velocity, heat, and mass flux. The Laplace transform technique is performed to obtain the solution in terms of repeated integrals of complementary error functions. The numerical values of surface shear stress, wall temperature, and concentration functions for different values of Prandtl number, Schmidt number, suction velocity parameter, and permeability parameter are reported in tables while the velocity, temperature, and concentration profiles are shown in figures. The results obtained are discussed for the case of most common interest, viz. cooling of the porous wall.
