...Ben Zhao; Teng Zhou; Ce Yang Surge is a crucial problem for achieving a good working range of centrifugal compressor and power cycle safety. Effective and early detection of the surge is essential to avoid its onset. In this paper, experiments measuring the pressure and acoustic signals have been...

...Ryosuke Seki; Toshihiko Azuma; Junji Iwatani; Akihiro Nakaniwa; Hidetaka Okui; Takanori Shibata In this article, an unsteady tip leakage flow instability is identified and investigated for an axial compressor at near-surge conditions. We describe the results of experimental verification of a new...

... to their compact size and ability to deliver high-pressure ratios over a wide range of flowrates. Methods to improve compressor efficiency near surge without reducing the surge margin have received considerable interest in the past. In many situations, changes to the impeller blade design and/or diffuser...

...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...

...Fangyuan Lou; Herbert M. Harrison; Nicole L. Key The identification of stall inception mechanisms and stability-limiting components in a centrifugal compressor is required for the development of effective surge suppression approaches. Part I of this two-part paper investigates the surge signature...
