NON-LOCAL EFFECTS IN THE STABILITY OF FLOW BETWEEN ECCENTRIC ROTATING CYLINDERS
The linear stability of the flow between two long eccentric rotating circular cylinders is considered. The problem, which is of interest in lubrication technology, is an extension of the classical Taylor problem for concentric cylinders. The basic flow has components in the radial and azimuthal directions and depends on both of these co-ordinates. As a consequence the linearized stability equations are partial differential equations rather than ordinary differential equations. Thus standard methods of stability theory are not immediately useful. By letting the clearance ratio and eccentricity tend to zero in a given way a global solution to the stability problem is obtained.
