A Criterion of the Oil/Gas Two-phase Flow Pattern in Aeroengine Bearing Chamber
摘要
Abstract
It is a potential method of reseach on two-phase oil/gas flow lubrication in aeroengine bearing chamber based on flow pattern classification, in which the identification to oil/gas two-phase flow pattern in bearing chamber is an important work. Based on the relationships between the two-phase oil/gas flow pattern and the match of geom- etry and operating condition in bearing chamber relying on nondimensional parameters and mean splashing parame- ter, a new method was proposed to identify flow pattern flow pattern identification by the present method agreed of oil/gas two-phase flow. The results of two-phase oil/gas well with the former experimental results. The present work realized evaluation of two-phase flow pattern according to the geometry and operating condition in bearing chamber, and it is conducive to analyzing two-phase oil/gas flow lubrication and designing heat transfer.关键词
