    Abstract
  • Tests were performed on aero-engine centrifugal separator to gain the performance data by simulating bearing cavity oil-air mist environment.Mass and optics measurement methods were used to collect the separating efficiency，particle size distribution and pressure drop data.Test results revealed that separating efficiency increased linearly and then gently while rotation increased.Separating efficiency increased 10% while rotation increased from static state to 1 000 r/min，particles between 2.0 μm and 3.0 μm were nearly separated，and middle diameter decreased from 1.8 μm to 1.3 μm.While rotation increased up to 2 500 r/min，middle diameter kept the same and particles below 2.1 μm were kept.Air mass flow nearly had no effect on particle size distribution and separating efficiency.Pressure drop increased when air mass flow and rotation increased.
