Research into Configuration and Flow of Wall Oil Film in Bearing Chamber Based on Droplet Size Distribution

The lubrication design and heat transfer determination of bearing chambers in aeroengine require a sufficient understanding of the oil droplet-film interaction and physical characteristic in an oil/air two-phase flow state.The analyses of oil droplet movement,mass and momentum transfer during the impingement of droplet/wall,as well as wall oil film thickness and flow velocity are very important for the bearing chamber lubrication and heat transfer calculation.An integrated model in combination with droplet ...
