Critical pressure drop ratio of superheated steam

Hello everyone, I would like to ask what the critical pressure drop ratio for superheated steam is What are the respective range for the subcritical and supercritical pressure drop ratios? I saw a statement online; I’m not sure if it’s correct. It says that at the critical state, the pressure drop ratio for superheated steam is q=0.546. Since the pressure of the gas source is high, the pressure ratios for various stages are chosen to be close to those of the critical state. After consulting relevant information, it was found that using subcritical conditions yields better noise reduction effects compared to designing using critical conditions; therefore, this design adopts subcritical conditions, with q set at 0.45. ”Is what he said correct regarding q=0.45? For example, will flow blocking occur when q=0.45? That’s what I think. If the critical value is 0.546, then subcritical values are those greater than 0.546, while supercritical values are those less than 0.546. Is that correct? Thank you!
I really haven’t used this before; I’ll show it to a few experts here~ @arpcd Brother Dao, how should we approach this issue?
The original poster is right; for articles on the Internet, they get passed around from one person to ten, and then to hundreds. To determine whether they are true or not, one should rely on their own judgment.
