EFFECTS OF TRANSVERSE OSCILLATIONS ON NATURAL CONVECTIVE FLOW INDUCED BY COMBINED THERMAL AND MASS DIFFUSIONS IN POROUS MEDIA

This paper studies the unsteady heat and mass natural convection in a highlyporous medium bounded by an infinite vertical porous wall. The unsteady sourceof the problem arises from the transverse oscillations in suction velocity offluids, The analytical results for the problem are obtained based on the methodof small parameter, and show that the natural circulation in the porous mediumis affected by this kind of oscillation.
