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,…

Detached eddy simulation of shock unsteadiness in an over-expanded planar nozzle
Emanuele Martelli, Pietro Paolo Ciottoli, Matteo Bernardini +2
This work investigates the self-excited shock wave oscillations in a three-dimensional planar over-expanded nozzle turbulent flow by means of Detached Eddy Simulations. Time resolv…
