The two-phase flow field in the high speed centrifugal oil-air separator of the aero-engine was numerically simulated by the Euler-Lagrange method. Numerical calculation was applied to analyze the influences of speed and mass flow rate on pressure drop and separation efficiency in a high speed centrifugal oil-air separator. The results indicate that the structural improvement of the rotating hollow shaft has obvious influence on reducing pressure drop and increasing separation efficiency.
