Effect Investigation of the Circumferential Grooves on the Static Characteristics of Hydrodynamic Journal Bearing Using CFD Method

Abstract:

The performance of a hydrodynamic journal bearing with different center circumferential grooves (CGs) is investigated using Computational fluid dynamics (CFD) simulation. The influences of the CG extended angel have been investigated based on the numerical model. The results show that the CG of millimeter range depth in load zone is not good for the bearing performance but it is opposite in unload zone.
