Assessment of heat transfer and Mach number effects on high-speed turbulent boundary layers
Michele Cogo, Umberto Baù, Mauro Chinappi +2
High-speed vehicles experience a highly challenging environment in which the free-stream Mach number and surface temperature greatly influence aerodynamic drag and heat transfer. T…
High-speed turbulent flows towards the exascale: STREAmS-2 porting and performance
Srikanth Sathyanarayana, Matteo Bernardini, Davide Modesti +2
Exascale High Performance Computing (HPC) represents a tremendous opportunity to push the boundaries of Computational Fluid Dynamics (CFD), but despite the consolidated trend towar…
Unsteadiness characterisation of shock wave/turbulent boundary-layer interaction at moderate Reynolds number
Matteo Bernardini, Giacomo Della Posta, Francesco Salvadore +1
A direct numerical simulation of an oblique shock wave impinging on a turbulent boundary layer at Mach number 2.28 is carried out at moderate Reynolds number, simulating flow condi…
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…
STREAmS: a high-fidelity accelerated solver for direct numerical simulation of compressible turbulent flow
Matteo Bernardini, Davide Modesti, Francesco Salvadore +1
We present STREAmS, an in-house high-fidelity solver for large-scale, massively parallel direct numerical simulations (DNS) of compressible turbulent flows on graphical processing…
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,…
