Abstract

The paper presents a methodology of modeling fixed geometry journal bearings with gas and oil lubrication. The general CFD package ANSYS is employed to simulate cavitated and turbulent flows. A grid independence study is performed for the oil-lubricated bearing. The CFD predictions are compared with the results obtained by traditional methods (reference books and using the Reynolds equation of lubrication). The discussion of the adequacy of the model is provided.
