Abstract
The influence of the flow regime on tilting-pad journal bearing perfor mance is presented. Three turbulent models are studied. The results sh ow that for high rotational speeds the effect of nonlaminar flow on th e predicted performance is not negligible. At high speeds, lower tempe ratures and greater power losses are obtained. Isotherms determined wi th laminar and turbulent models help to explain this phenomenon.
