Abstract
The influence of the airflow bypass at the impeller input on the operational stability of a compressor is considered. The bypass structure is discussed, and a new chamber design is proposed for a compressor with diffuser blades. Numerical analysis of the flow structure is conducted. The compressor’s margin of operational stability is assessed experimentally for bypass chambers of different geometry.
