Study on the Effect of Two-Phase Flow Model on Oil Film Properties of Sliding Bearing

摘要

This paper analyzes the hydrodynamic pressure of journal bearing, and studies the oil film characteristic and the distribution of cavitation at different inlet pressures and viscosities using two phase flow model of Fluent. The experiment results demonstrate that the static pressure of oil film increases with the increase of lubricating oil viscosity and the input pressure has almost negligible effect on the distribution of oil film. Cavitation of the oil film generates some influences when there are changes in the viscosity and input pressure.
