Heat and Mass Transfer of A MHD Flow of a Nanofluid Through a Porous Medium in an Annular, Circular Region with Outer Cylinder Maintained at Constant Heat Flux

Abstract

In this paper we consider the unsteady thermal convection due to the imposed traveling thermal wave boundary through a vertical channel bounded by flat walls. Before in few papers have discussed the two dimensional free and forced convection flow and heat transfer in a vertical wavy channel with traveling thermal waves embedded in a porous medium but here we are considering The effect of free convective heat and mass transfer flow have been discussed by solving the governing unsteady non-linear equations under perturbation scheme. The velocity, the temperature and the concentration have been analyzed for different variations of the governing parameters. The shear stress, rate of heat transfer and rate of mass transfer have been evaluated and tabulated for these sets of parameters and also from tables we analyze rate of heat and mass transfer for different parametric values.
