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.

Starvation in Ball Bearing Lubricated by Oil and Air Lubrication System
1998An oil and air lubrication system for ball bearings supporting a high speed spindle maintains friction losses and temperature rises in low level comparing with other lubrication systems, e.g., oil jet or oil mist lubrication. In this study, rotating speeds of the ball in an angular contact ball bearing lubricated by the oil and air lubrication system ...

Study of an Air-Oil Pump and Separator Solution for Aero Engine Lubrication Systems
Volume 2: Aircraft Engine; Coal, Biomass and Alternative Fuels; Cycle Innovations, 2013Lubrication system of aero engines have to manage a two-phase flow of oil and air created in air-sealed bearing chambers. A part of this flow goes through scavenge pumps and a de-aerator before returning to the tank, the other part passes through a de-oiler before leaving the engine.
