Abstract

Abstract For an aero turbo-shaft engine, rain water enters the intake protection device and the morphology of water droplets after hitting the wall will affect the internal flow of the compressor. In this paper, Sommerfeld number was used to determine the shape of water droplets after they hit the wall. The flow field and characteristics of the compressor with inlet particle separator under different water ingestion conditions were studied with considering the impact of water film and droplets splashing near the wall. The results show that the entry of water droplets deteriorates the internal flow field of the compression component, and the water film affects the flow state of the airflow near the wall. Compared to the effect of the splashing factor, the viscous resistance effect of water film near the wall on the airflow and boundary layer can cause a significant reduction in the characteristics and stability of the compressor.

带入口颗粒分离器的压缩机吸水性能研究

摘要对于航空涡轴发动机，雨水进入进气保护装置，水滴撞击壁后的形态会影响压缩机的内部流量。在本文中，Sommerfeld数被用来确定水滴撞击墙壁后的形状。研究了带入口颗粒分离器的压缩机在不同进水条件下的流场和特性，并考虑了壁面附近水膜和液滴飞溅的影响。结果表明，水滴的进入破坏了压缩部件的内部流场，水膜影响了壁附近气流的流动状态。与飞溅因子的影响相比，壁面附近水膜对气流和边界层的粘性阻力效应会导致压缩机的特性和稳定性显著降低。
