摘要：

In order to study the separation performance of the dynamic pressure oil-gas separator, a crucial part in lubricating system of aero engine, bubble trajectory model is used to study the effect of rate of flow, tangential velocity of flow at the inlet and diameter of the separator on the separation efficiency. The results show that when the flow rate of oil changes in 4~20L/min, the separator can reach the best separation performance as the diameter of separator is 15mm. When the average axial velocity of oil is less than 0.35m/s, the separation efficiency of the separator increases with the increase of the flow rate of oil. When the average axial velocity of oil is greater than 0.35m/s, the separation efficiency of the separator decreases with the increase of the flow rate of oil.
