Unsteady flow of a dusty eiastico-viscous liquid in the Ekman layer

Abstract

The transient flow in the Ekman layer of a dusty elastico-viscous liquid near a flat plate is discussed. Initially the dusty fluid and the plate were rotating together and the plate then suddenly starts moving with a uniform velocity in its own plane relative to the rotating frame of reference. The effect of rotation manifests itself through inertial oscillations which decays exponentially with time. It is shown that the frequency of inertial oscillations decreases with increase in either mass concentration or elastic element in the liquid.
