Micro-Roughness Effects in (Elasto)Hydrodynamic Lubrication Including a Mass-Flow Preserving Cavitation Model
Résumé
An average Reynolds equation is proposed for predicting the effects of deterministic periodic roughness, taking JFO mass flow preserving cavitation model and elastohydrodynamic effects into account. For this, the asymptotic model is based upon double scale analysis approach. The average Reynolds equation can be used both for microscopic interasperity cavitation and macroscopic one. The validity of such a model is verified by numerical experiments.
