Abstract

The present article deal with deportation Calidity and conglomeration transposition flow over a permeable passable in a rectangular duct with  effects of gratification effects , chemical reaction and  radiation. With the help of finite element analysis(Galerkin method) with three nodded triangle elements we solved  governing equations of flow heat and mass transfer. The ratio of momentum diffusivity P is taken to be 0.71. In this analysis we found the change in Sherwood number and Nusselt number (Nu) with respect to different parameters. In view of different parameters like Soret effect and radiation effect on non dimensional temperature, concentration has been discussed. This  numerical results shown  two different fluid  flow systems related to the ratio of external Raleigh numbers  together with the internal energy. Also, it was found that along the cold wall increased with higher external Rayleigh numbers and lowering with internal Rayleigh numbers. The Literature advocates that the variation of viscous dissipation with different geometries on heat transfer as been studied.  By finite element analysis  we analyses the mass and heat  transfer in Porous Rectangular Cavity wit different parameters at  side walls.  Also we observed the thermal radiation acts convincing part in comprehensive surface fieriness displacement with lowering in heat transfer.
