Sonic choked flow of a gas

WebJul 24, 2024 · If the nozzle pressure ratio is high enough, then the flow will reach sonic velocity at the narrowest point (i.e., the nozzle throat). In this situation, the nozzle is said to be choked. WebAug 5, 2016 · The sonic or critical or choked condition, as it is called, appears to block any information which is trying to penetrate upstream. A simple picture of this is that the messengers carrying such information travel at the speed of sound, and so they are unable to make any headway over the fast-flowing gas stream. Two important effects of this are ...
