摘要
对某低速压气机在设计转速下从设计工况点向小流量工况点发展直至发生喘振的运行过程进行了试验 ,并在第 2级静叶出口截面进行了详细的流场测量。试验结果表明 ,当流量减小时 ,在测量截面上有明显的大范围分离流动特征。经过对比分析 。
Experimental investigation of the flow field in approaching surge was conducted at the design speed for a low-speed two-stage compressor, and the measurements of the flow fi eld were made at the 2nd stage stator row exit. The results show that the separa ted flow is evidently extended with the reduced mass flow. It can be concluded t hat the separated flow with approaching surge occurs at the stator exit.
