| 摘 要： | 为了研究航空发动机滑油系统中的关键部件动压式油气分离器的分离性能,采用气泡轨迹模型研究了滑油流量、进口处滑油的切向速度和分离器直径对滑油区内气泡分离效率的影响。结果表明:增大进口处滑油的切向速度能够提高分离性能;当滑油流量在420L/min变化时,筒径为15mm的分离器的分离性能最佳;滑油沿分离器筒体方向的平均轴向速度小于0.35m/s时,分离器的分离效率随滑油流量增大而增大;滑油沿分离器筒体方向的平均轴向速度大于0.35m/s时,分离器的分离效率随滑油流量增大而减小。

| Abstract: | 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. |
