Abstract

An exact solution of the time-dependent Navier-Stokes equations is obtained for the flow between eccentric rotating disks. It is shown that the flow can be two-dimensional if a convenient initial condition is specified, although when the disks are impulsively started from rest, the flow becomes three-dimensional. An analytical solution describing the flow at small and large times after the start is obtained by the Laplace transform method.
