Abstract A theoretical analysis of the performance characteristics of axially undefined journal bearings was carried out. The analysis takes into account the velocity slip at the surface of the porous medium by using the Beavers-Joseph criterion. Results are presented for various bearing characteristics and compared with earlier results obtained by using the no-slip condition.

Abstract The analysis of the squeeze film between two rotating annular discs, one with a porous facing, is extended to include the effect of velocity slip at the porous surface through the Beavers-Joseph slip model. The problem is solved analytically using the separation of variables method. The effect of slip is to reduce the load capacity and the response time of the squeeze film.

Abstract The analysis of the squeeze films between porous discs of various shapes is extended to include the effect of velocity slip at the fluid and porous material interface. Modified equations for calculating the pressure, load carrying capacity and the film thickness and time relation are presented. A simple mathematical analogue for determination of the squeeze film behaviour for porous discs with slip consideration from the already available solution (without slip) is given.

Abstract Squeeze film behaviour in a narrow porous journal bearing is analysed. The analytical model takes into account the effect of porosity by assuming that the flow in the porous matrix obeys Darcy's law. The modified Reynolds' equation is derived to account for the porosity of the bearing. The expressions for pressure distribution and load capacity are given in closed form while the time-height relation is obtained by numerical integration. The results are shown graphically for selected par...

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 infinitesima...
