涡轮中的激波/叶排相互作用

SHOCK WAVE/BLADE INTERACTION IN TRANSONIC TURBINE

本文对涡轮中激波／叶排干扰进行了初步研究。结果表明，关于激波／叶排干扰的认识是无导叶对转涡轮研制的重要理论基础。此外，激波／叶排干扰是存在该现象的涡轮所受高周交变力的主要原因，要解决这类涡轮的高周疲劳问题（ＨＣＦ）必须深入研究激波／叶排干扰．

Primary studies about shock wave/blade interaction are presented. It is shown that the knowledge about shock wave/blade interaction founds the basis for the design of vaneless counter-rotating turbine. Additionally, The SW/B interaction is the main reason of turbine High Cycle Fatigue(HCF). A more deep understanding about SW/B interaction will attenuate the problem of HCF.
