Flow dynamics and wall-pressure signature in high-Reynolds number overexpanded nozzle with free shock separation

E. Martelli, L. Saccoccio, P. P. Ciottoli +3

A delayed detached eddy simulation (DDES) of an overexpanded nozzle flow with shock-induced separation is carried out at a Reynolds number equal to 1.7 10^7. The flow unsteadiness,…
