Unsteady flow of dusty visco- elastic liquid between two oscillating plates

Abstract

The unsteady flow of dusty visco-elastic liquid (Kuvshmiski type) between two oscillating plates is considered in view of its growing importances in various technical problems. The analytical xpressions for the velocities of liquid and dust particles are obtained by the technique of Laplace transform. The effects of elastic elements in the liquid, the mass concentration and the relaxation of dust partlcle on the velocity fields, the skin friction at the lower plate and the volume no* in between the plates are presented numerically, graphically. It is found that both skin friction at the lower plate wall and volume flow will between the plates increase In the presence of the elastic element in the liquid.
