Analysis of Wave Motions of a Viscous Incompressible Fluid on a Rotating Wall in the Presence of a Cross Flow

The non-stationary problem of wave motions of a viscous incompressible fluid on a rotating plate is considered. An analytical solution of three-dimensional time-dependent hydrodynamic equations is given. The velocity field in flow of a viscous fluid that occupies half-space bounded by a plane wall is determined. The fluid together with the bounding plane rotates as a single whole at a constant angular velocity about a direction non-perpendicular to the plane. Non-stationary flow is induced by suddenly starting longitudinal oscillations of the wall and by injection (suction) of the medium produced along the normal to the wall surface. A number of special cases of wall motion are considered. Based on the obtained results, individual structures of the boundary layers near the wall are investigated.
