Comparison between three turbulent models - application to thermohydrodynamic performances of tilting-pad journal bearings

摘要

The influence of the flow regime on tilting-pad journal bearing performance is presented. Three turbulent models are studied. The results show that for high rotational speeds the effect of non-laminar flow on the predicted performance is not negligible. At high speeds, lower temperatures and greater power losses are obtained. Isotherms determined with laminar and turbulent models help to explain this phenomenon.
