Centrifugal breather is the major part of lubricating oil recycling system in aviation engine, whose efficiency of oil-separation can be affected by air flow and speed.The transmittance of oil droplets under different conditions is calculated with the subjects of the two-phase flow in the Centrifugal breather which is consisted of air and oil particles, The DPM model is used to simulate the jet source of particles, and the Reynolds stress model is applied to calculate continuous phase turbulent flow.The results show that icreasing the speed can reduce transmittanceand ensure oil recovery, and thatthe more the ventilation flow, the more the penetration of centrifugal breather.
