EFFECT OF NON-UNIFORM TEMPERATURE GRADIENT ON A FLUID LAYER OVERLYING LAYER OF POROUS MEDIUM WITH VARIED SPECIES CONCENTRATION

摘要

This paper deals with effect of non-uniform temperature gradient on a fluid layer overlying layer of porous medium with varies species concentration The problem is constituted with the basic equations of continuity, momentum, energy and concentration. Here the density of the medium is varied in accordance with the change of temporaturo and concentration. Alter non-dimensionlising the basic equations, solutions are obtained for velocity, temperature and concentration of the flow. After necessary numerical simulation by the computer, temperature profiles are plotted. It is observed that the temperature changes with the distance 'Z' in a parabolic shape.
