摘    要:以低速单级压气机为研究对象,根据引气对压气机性能的影响机理设计了6种引气方案,通过数值模拟,讨论了引气对压气机总压升、稳定裕度的影响.结果表明:对于角区大分离的静子,在靠近吸力面的机匣上和叶片吸力面近轮毂区域同时引气可以以较小的引气量获得压气机总压升和稳定工作裕度的全面提升.研究结论有力地支持了空气系统气源引气与压气机...

关 键 词:压气机  引气  总压升  稳定裕度  空气系统

Abstract:By analyzing the low-speed single-stage compressor,six different bleed ing plans were presented according to their influence mechanism on the compresso r performance.A numerical simulation was conducted to study the influence of ble eding on the compressor's total pressure rise and stability margin.The results show that,for the stators with large flow separation in the corner,it is better to bleed air both from the suction surface of the casing and the blade suction s urface near the hub simultaneously,so a...
Keywords:compressor  bleed air  total pressure rise  stability margin  air system
