Mass Conserving Elastohydrodynamic Lubrication Model of Engine Bearings with an Oil Passage: Effects of Surface Textures and Pressure-Viscosity Relation on Friction

摘要

An average flow model of surface textures, namely roughness and striations, and pressure-viscosity relation are included in a mass conserving elastohydrodynamic lubrication model of bearings with an oil passage in which change in density, fill fraction and continuity of oil in time and space are considered with the modified Elrod's cavitation algorithm.
