Dispersion Effects on Mixed Convection over a Vertical Wavy Surface in a Porous Medium with Variable Properties

Abstract

In this paper, the dispersion effects and variable properties on mixed convection over vertical wavy surface immersed in a fluid saturated Darcy porous medium are considered. The governing equations are transformed into a set of ordinary differential equations using the similarity transformation and then solved numerically. The numerical results obtained in the present method compared with previously published results and are found to be in good agreement. The variation of the velocity, temperature and concentration as well as rate of heat and mass transfers are presented graphically for various values of pertinent physical parameters.
