Flow Between Eccentric Rotating Cylinders

Abstract

The flow between eccentric rotating cylinders is studied using a modified bipolar coordinate system. The Sommerfeld pressure distribution and associated flow in a journal bearing are derived from the Navier-Stokes equations by a straightforward and systematic expansion in the clearance ratio (assumed small). First order corrections for curvature and inertial effects are given. There is no restriction on the eccentricity.
