摘要

This document calculates and discusses circular groove angle (CGA) affects on journal bearing performance. CFD method has been used for calculate N-S equations and cavitation effect has been considered. The results show that as CGA increases, the maximum pressure is decreased; the capacity and friction moment are also decreased. The maximum pressure position is increased from 1 to 2 when CGA is 180°. This paper will provide a theoretical basis for journal bearing groove optimal design.
