Abstract
The “negative squeeze” lubrication problem is investigated by means of a mass-conservating finite element cavitation algorithm (described elsewhere) within the context of a dimensionless study of lubricant film behavior between rigid, parallel separating surfaces. Appropriate mesh geometries which capture spatial and temporal mixture density history and satisfy JFO conditions on the cavitation interface are determined. Present simulation results agree qualitatively with previous experiments, supporting the validity of the algorithm and its utility in the bearing design process.
