Centrifugal compressor performance curve
Thread Content
Could the experts please explain the aerodynamic curve of centrifugal compressors?
What are the characteristics of the characteristic curve of a centrifugal compressor? ①There is a corresponding characteristic curve for each rotational speed. ②There is a maximum traffic limit. ③There are minimum flow limits and surge boundaries. ④Stall margin. ⑤Stable workspace.
1. Flow rate – shaft power 2. Flow rate – outlet pressure 3. Flow rate – specific energy head 4. Flow rate – polytropic efficiency. However, the rotational speed can also be taken into account; thus, different curves can be obtained for various rotational speeds. Please find one and take a close look at it
