What is the difference between the compressor stone wall phenomenon and the stagnation phenomenon?
Thread Content
Recently, I have been learning about knowledge related to compression units; there is a stone wall line at the outlet of the second stage of the propylene refrigeration compressor. Regarding the pyrolysis gas compressor, it is mentioned that the maximum suction flow rate cannot exceed the stagnation flow rate. What is the difference between these two?
The two are unified; in short, it is the \"choked condition\" – compressors reach their maximum flow rate at this point, and the gas flow velocity reaches the speed of sound, representing an unstable operating condition for the compressor.
