Clean Sky 2 Call for Proposals 02 · Analysis of centrifugal compressor instabilities occurring with vaneless diffusor, at low mass flow momentum

Specific Challenge:The performance of compressors at low mass-flows is characterized by the occurrence of unsteady flow phenomena surge and rotating stall. These instabilities can cause noise nuisance and critical operating conditions with strong dynamical loading on the blades. Such phenomena must…
