Air-oil lubrication has been widely used for high-speed spindle bearings because its oil delivery is positive and can be controlled very accurately. In this study, the effects of air-oil lubrication conditions, such as the oil discharge quantity, oil discharge interval, oil viscosity, air supply rate and tube length, were analyzed with respect to the ...

Development of Air Lubrication System for Reduction of Ship Frictional Drag
2019Frictional resistance occupies a large portion of the total resistance of a vessel accounting for nearly 60 ~ 80%, and lower friction resistance can lead to a remarkable reduction in greenhouse gas (GHG) emissions from ships. Air lubrication is widely recognized as one of the useful technologies to reduce a ship’s frictional resistance by injecting air

The Improvement of Air/Oil Separator Performance in the Aero-Engine Lubrication System
Volume 9: Oil and Gas Applications; Supercritical CO2 Power Cycles; Wind Energy, 2017Air/oil separator plays an important role in the aero-engine lubricating oil system, and connects oil cavity and atmospheric environment, where it is used to separate oil from oil-gas two-phase flow and reduce the consumption of lubricating oil. Oil-gas separation efficiency and flow resistance are two key performance parameters of the separator.
