Compresseur centrifuge : régulation multimodale rotative.

Centrifugal compressor multi-mode rotating stall control.

Auteurs : DAY E. C., LAWLESS P. B., FLEETER S.

Résumé

To maintain stable operation, centrifugal compressors require a sufficient surge margin to avoid instabilities caused by small deviations in operating point or inlet conditions (rotating stall and surge). Recent efforts in stall control have focused on the suppression of a single resonant mode. A critical limitation of these techniques has been the eruption of higher order modes. To address this issue, experiments have been performed at Purdue University to investigate the feasibility of passive control of multi-mode rotating stall in centrifugal compressors. These experiments are described.
