摘要：
In order to investigate its separation performance and establish the method for calculating the separation efficiency compliant with the requirements of engineering design, stress analysis of oil droplet was conducted, the trajectory model of oil droplet was established, and the minimum oil drop diameter under different conditions was calculated combining with the oil droplet capture condition, finally realizing the theoretical calculation of impeller ventilator separation efficiency. Research showed that in different speeds, mass flow rates, and inlet temperatures, the separation efficiency and the minimum separation diameter were in agreement with the experimental values; the maximum errors of separation efficiency were 0.95%, 1.01% and 1.01%, respectively; the maximum errors of the minimum separation diameter were 1.33%, 2.29% and 6.20%, respectively. The calculation results were in good agreement with the experimental results. This method can provide a reference for designing the impeller type ventilator and optimizing its separation performance. © 2018, Editorial Department of Journal of Aerospace Power.
