Investigation of velocity slip effect on steady state characteristics of finite hydrostatic double-layered porous oil journal bearing

摘要

Steady state characteristics of finite hydrostatic double layer porous oil journal bearing are investigated theoretically by incorporating tangential velocity slip at the porous-film interface given by Beavers-Joseph. The governing equations for flow in the porous medium and modified Reynolds equation in the film region are solved simultaneously using finite difference method. The effects of slip and design variables such as feeding parameter, bearing number, eccentricity ratio, slenderness ratio, and anisotropy of permeability have been investigated on bearing performance characteristics like load-carrying capacity, attitude angle, friction variable, and volume flowrate. The results are depicted in the form of graphs that can be utilized during design.
