Analysis of Narrow Porous Journal Bearing Using Beavers-Joseph Criterion of Velocity Slip

Abstract

Analytical solution for performance characteristics of a narrow journal bearing is obtained. The analysis takes account of the velocity slip at the surface of a porous medium by using Beavers-Joseph criterion [1]. Results are presented for various bearing characteristics and compared with earlier results obtained by using no-slip condition. A comparison is also made with an earlier approximate analysis [8] which considers the slip effects but assumes the bearing wall thickness to be infinitesimally small.
