Passive flow-separation control in a dual-bell rocket nozzle
Matteo Cimini, Emanuele Martelli, Matteo Bernardini
A delayed detached eddy simulation of a sub-scale cold-gas dual-bell nozzle flow at high Reynolds number and in sea-level mode is carried out at nozzle pressure ratio NPR=45.7. In…
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,…
Numerical investigation of supersonic shock-wave/boundary-layer interaction in transitional and turbulent regime
Russell Quadros, Matteo Bernardini
We perform direct numerical simulations of shock-wave/boundary-layer interactions (SBLI) at Mach number M = 1.7 to investigate the influence of the state of the incoming boundary l…
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…
Heat transfer and wall temperature effects in shock wave turbulent boundary layer interactions
Matteo Bernardini, Johan Larsson, Sergio Pirozzoli +1
Direct numerical simulations are carried out to investigate the effect of the wall temperature on the behavior of oblique shock-wave/turbulent boundary layer interactions at freest…
DNS of laminar-turbulent boundary layer transition induced by solid obstacles
Paolo Orlandi, Sergio Pirozzoli, Matteo Bernardini
Results of numerical simulations obtained by a staggered finite difference scheme together with an efficient immersed boundary method are presented to understand the effects of the…
