Surge in centrifugal compressors is a phenomenon that can occur when:
1
The flow rate of the gas is increased beyond the maximum design flow rate
2
The pressure of the incoming gas is decreased beyond a set value
3
The temperature of the incoming gas is increased beyond a threshold
4
The flow rate of the gas is reduced below a critical value
