...-lubricated journal bearings, a turbulent flow model considering cavitation effect was proposed on the basis of two-phase flow theory. The simulation was conducted to show the influence of turbulence and cavitation effects on the static characteristics of the water-lubricated journal bearing. The proposed...

..., and the air volume fraction can be adjusted conveniently to reach a high value. Based on this, in Part 2, we intend to explore the feasibility of using the bubbly oil in lubricating high-speed bearings. Here, we select a step thrust bearing as object and analyze its static characteristics under the bubbly oil...

... and high nonlinearity. It is demonstrated that the fixed end of the foil structure affects the static characteristics of the bumps by observing whether the local hysteresis loops of different bumps track the global hysteresis loops. It is apparent that the bumps on the left side of the rotor center during...
