粒子分离器结构优化对吞雨性能改进研究
Investigation on rain-swallowing performance improvement by structure optimization of a particle separator
摘要
Abstract
The Eulerian-Lagrangian multiphase flow particle tracking model was used to numerically simulate the particle separator in a turboshaft engine,and the theory of orthogonal experimental design was employed to conduct the experiment and optimize the structure of the particle separator.The effects of the structure parameter of the par-ticle separator on the separation effect and rain-swallowing performance were examined.The results disclosed that,compared with the original model,in dry conditions,the scavenging ratio of the optimized model decreased by 4.3%,and the total pressure loss coefficient decreased by 0.03%;in rain-swallowing conditions,the former de-creased by 0.97%,the latter decreased by 0.039%,and the separation efficiency increased by 5.5%.Therefore,this optimization design basically satisfies the requirements of low total pressure loss and high separation efficiency.In addition,the rain-swallowing performance of the particle separator is improved to a great degree.关键词
