title = "Numerical study on the effect of oil removal from aero-engine bearing chamber and improvement",
abstract = "Effective oil removal from the scavenge is essential to improve the oil distribution in the bearing chamber and avoid excessive heat generation, especially under the high rotation speed. In this paper, based on an simplified bearing chamber, two oil-return structures for scavenge offtakes (ramp sump and eccentricity sump) are designed and improved, the oil-gas two-phase flow model with Volume of Fluid (VOF) is proposed, and characteristics of two-phase flow field and oil-return efficiency from the scavenge are calculated in ANSYS-Fluent version 14.5. The results show that it is effective to maintain the high oil-return efficiency under the high rotation speed by improving oil-return structures, and the oil film accumulation on the bearing chamber wall can also be improved to a certain extent.",
