Numerical Modeling of Fluid’s Aeration: Analysis of the Power Losses and Lubricant Distribution in Gearboxes [PDF]
Journal of Applied and Computational Mechanics, 2023 Aeration determines the entrainment of air in another fluid. In geared transmissions, this process affects the operating temperature of the mechanical system because the air’s bubbles trapped in the lubricant act as an insulator.

Development of an oil-air lubrication system with a piezoelectric nozzle for machine tool spindles.
JSME international journal. Ser. 3, Vibration, control engineering, engineering for industry, 1988 Oil-air lubrication is one of the effective lubrication methods for the high-speed spindle of machine tools. However, the oil supply rate to the bearing fluctuates remarkably due to the intermittent oil supply from the oil-air mixing valves. In this study, a new oil-air mixing equipment is developed by applying the piezoelectric nozzle which has been ...
