本文采用欧拉-拉格朗日多相流粒子追踪模型对某型涡轴发动机粒子分离器进行了数值模拟，利用正交试验设计的原理进行试验并完成了对粒子分离器结构的优化，研究并揭示了粒子分离器结构参数对其分离效果和吞雨性能的影响规律。结果表明:在干工况条件下，与原型相比，优化后的模型扫气比降低 4。3%，总压损失系数降低0。03%;在吞雨工况下，相比于原型，优化后的模型扫气比降低 0。97%，总压损失系数降低 0。039%，分离效率提高5。5%。本次结构优化基本达到了粒子分离器低总压损失高分离效率的优化要求，并且对粒子分离器吞雨性能有较大的提升。
Investigation on rain-swallowing performance improvement by structure optimization of a particle separator
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.
