    Abstract
  • In order to analyze the influencing factors of flow resistance in the oil-air separator of the aero-engine, flow field in the oil-air separator was caculated numerically using computational fluid dynamics (CFD) and Reynolds stress model (RSM). The flow resistance of calculation and experiment under the same operating conditions were compared to ensure the applicability of the model. Enough number of flow resistance values of different operating conditions and structures had been calculated for the binary quadratic space trend surface regression. The results show that the increasing of flow rate and rotational speed will bring greater flow resistance. The design of the breather hole eccentricity and the reducing the plate tip radius can reduce the flow resistance, the breather hole eccentricity design has the best eccentricity about 7.5mm.
