Application of the CE/SE Method to Wave Journal Bearings

Abstract

The space-time conservation element and solution element (CE/SE) method, successfully used to solve a wide variety of compressible flow problems, is extended for the first time to predict the effects of gaseous cavitation in moderate to heavily loaded wave hearings, including misaligned cases. Elrod's formulation is used for a two-dimensional, finite length hearing, and the intricacies of the CEISE scheme applied to solve this problem are presented. The numerical results obtained are compared with other numerical solutions to demonstrate the ability of the method to solve such problems.
