Converging diverging supersonic diffuser

WebSep 6, 2024 · You want the exhaust stream to have velocity. If it exits the nozzle with excess pressure, that extra pressure essentially gets converted into plume size (see the underexpanded streams on rocket first stages at high altitudes as an example). This is why subsonic nozzles converge, and supersonic nozzles converge to a Mach 1 throat and … Webobserved inside the diverging section as shown. •The region ahead of the shock in the diverging section is supersonic, while behind the shock the flow is subsonic. As a result, the Mach number decreases and the static pressure increases toward the exit. 𝑝 𝑝0 𝑀 0.528 𝑥 𝑥 ck Isentropic Solution (Supersonic) Isentropic Solution ...

WebIn this application, AcuSolve is used to simulate the high-speed turbulent flow in a converging and then diverging nozzle. The flow within the nozzle enters as subsonic, reaches sonic at the throat and shortly after develops a normal shock. AcuSolve results are compared with experimental results adapted from Bogar and Sajben (1983).
