Paper No: TURBO-22-1280
Published Online: November 25, 2022
...Julien Marty; Lionel Castillon; Pierric Joseph The operating range of a compressor is limited by surge or rotating stall line, among others. Numerical simulations must accurately predict these phenomena. This study is based on the experimental compressor CME2, which is a low-subsonic axial...

...Yoshihiro Hayashi; Teng Cao In centrifugal compressors, it is common to observe a rapid reduction in surge margin toward high rotational speed, which shows a non-linear surge characteristic against the change of rotational speed. This paper presents a comprehensive experimental and numerical study...
