Stalling In Compressor. Rotating stall is a local disruption of airflow that propagates around the compressor, reducing efficiency. Stall refers to local instability, indicating flow recirculation in the domain.
The instabilities limit the flow range in which the compressor can. A stall that results in the complete disruption of the airflow through the. On the other hand, surge is the final step of the.
These are known as surge and rotating stall. At low flow rates, rotating stall and surge are the fundamental limits of a. A stall that results in the complete disruption of the airflow through the. A rotating stall may develop into a surge.
