SOURCE FLOW BETWEEN TWO NON-COAXIAL ROTATING CYLINDERS

Abstract

Two-dimensional flow of an incompressible viscous fluid between two rotating non-coaxial cylinders bas been investigated when fluid is injected uniformly through the surface of the inner cylinder andTwieved through the surface of the outer cylinder. Under the assumption of small eccentricity,Sion of the governing Navier—Stokes equations is obtained for the case when the gap between the cylinders is finite. Solutions of the governing equations under the geometrical restriction of narrow gap are also presented. The effect of the radial flow or suction on the transverse velocityis discussed for the narrow gap_ The existence of force component in the x -direction on the inner cylinder is due to the radial flow.
