Unsteady behavior and mechanism of a rotating stall in a centrifugal compressor with vaneless diffuser

open access: yesNihon Kikai Gakkai ronbunshu, 2021
Unsteady diffuser stall behavior in a centrifugal compressor with a vaneless diffuser was investigated by experimental and computational analyses. The diffuser stall generated as the mass flow rate decreased. The diffuser stall cell rotated at 25-30 % of
