Free convection and mass transfer effects on the oscillatory flow of a dissipative fluid past an infinite vertical porous plate (I)

The effects of free convection and mass transfer on the oscillatory flow of an incompressible, dissipative, viscous fluid past an infinite vertical, porous plate with constant suction, is studied. The solution of the problem is obtained with assumption that there exists a “mean steady flow” and on it superimposed the unsteady oscillatory flow. The mean steady flow is studied in this paper and the effects of Grashof number (Gr), modified Grashof number (Gc), Eckert number (E) and Schmidt number (Sc) are discussed for the case of air ( P = 0·71). The study of the expression of the unsteady parts of the velocity, temperature and related quantities will be given in a subsequent paper.
