Effect of movable flat baffles plenum volume on pressure distortion flow field of engine

摘要

摘要: 基于移动插板容腔对发动机进气压力畸变流场影响,获取了移动插板容腔对小进口直径发动机流场扰动特性。通过发现问题、分析问题、数值模拟、改进设计与试验验证等技术过程,证明了移动插板容腔降低了进气压力畸变流场强度,其影响范围为进口直径小于200mm的发动机,且为避免移动插板容腔对发动机进口气流流场的扰动,设计压力畸变装置时应采取相应措施减小插板容腔体积。

Abstract: Based on the effect of movable flat baffles plenum volume on inlet pressure distortion flow field of engine, the destabilization characteristic of the movable flat baffles plenum volume on small flux tube engine air flow field was obtained. Through the process of problem discovery, analysis, numerical simulation, improved design, and test verification, the movable flat baffles plenum volume was proved in reducing the distortion intensity of inlet pressure flow field, and the engine of less than 200mm diameter flux tube was covered within the range of effect. In order to avoid destabilization to the inlet air flow field of the movable flat baffles plenum volume, corresponding measures should be taken to reduce the volume in the design of the pressure distortion device.
