| 摘 要： | 结合大小水滴模型和由大量试验数据得到的损失和落后角模型,采用两相流理论与数值模拟的手段,在来流含水的状态下计算了某型发动机压缩系统的特性;分别研究了来流含水量、水滴尺寸等对压气机性能的影响。结果表明:进口气流中水的含量以及它存在形式均对压缩系统性能有不可忽视的影响,同时也验证了本文方法有效性和应用价值。

| Abstract: | Numerical simulation and twophase fluid flow theory were employed to calculate the characteristics of engine compressor with inlet water ingestion.Droplet model,loss and deviation model corrected by test data were used in the calculation.The investigation of water content,droplet size etc.,which would affect the compressor performance,shows that inlet water content and size of droplets have significant influence on compressor performance.In addition the results indicate that this method is effective and valuable in engineering application. |
