Trying to achieve supersonic flow in a pipe CFD Online

Initially outlet flow is supersonic as soon as run starts to converge it drops down to subsonic because I increase the mass flux gradually density increases everywhere This is choking Supersonic flow should be very different highest velocity is at inlet gradually decreasing towards outlet and possibly becoming sonic M=1 there if the pipe is long enough Fanno flow

Why can t jet engines ingest supersonic air Quora

The thrust comes from equation F=ma = m Δv / t it is proportional to both mass of air pushed behind per time unit and the extra velocity the engine gives to the air So thrust can be increased either by pushing more air or pushing the exhaust at higher speed The energy required for pushing the exhaust comes from equation E=1/2 m Δv ^2

Supersonic aircraft Wikipedia

One approach to resolving this compromise is the use of a variable geometry wing commonly known as the swing wing which spreads wide for low speed flight and then sweeps sharply usually backwards for supersonic flight However swinging affects the longitudinal trim of the aircraft and the swinging mechanism adds weight and cost

Why does supersonic flight detach airflow from a wing

Short answer To go back from supersonic to subsonic flow Supersonic flow is hard to decelerate without a shock since the air molecules don t know what is ahead The speed of sound is also the speed of small pressure changes so any signals of what is coming will not reach the air ahead of the shock wave
