Mixed convective heat and mass transfer in a vertical wavy channel with traveling thermal waves and porous medium

We investigate the problem of mixed convection heat and mass transfer through a vertical wavy channel with porous medium. The flow is generated by the periodic thermal waves prescribed at the wavy walls of the channel. The equations of momentum energy and concentration are solved subject to a set of appropriate boundary conditions by assuming that the solution consists of a mean part and a perturbed part. The effects of various pertinent parameters on flow, heat and mass transfer characteristics are discussed numerically and explained graphically.
