A priori tests of turbulence models for compressible flows
Sciacovelli L., Cannici A., Passiatore D. +1
A priori tests of turbulence models for the compressible Reynolds-Averaged Navier--Stokes (RANS) are performed by using Direct Numerical Simulations (DNS) data of zero-pressure-gra…
Shock impingement on a transitional hypersonic high-enthalpy boundary layer
Donatella Passiatore, Luca Sciacovelli, Paola Cinnella +1
The dynamics of a shock wave impinging on a transitional high-enthalpy boundary layer out of thermochemical equilibrium is investigated for the first time by means of a direct nume…
Finite-rate chemistry effects in turbulent hypersonic boundary layers: a direct numerical simulation study
Donatella Passiatore, Luca Sciacovelli, Paola Cinnella +1
The influence of high-enthalpy effects on hypersonic turbulent boundary layers is investigated by means of direct numerical simulations (DNS). A quasi-adiabatic flat-plate air flow…
Assessment of a high-order shock-capturing central-difference scheme for hypersonic turbulent flow simulations
Luca Sciacovelli, Donatella Passiatore, Paola Cinnella +1
High-speed turbulent flows are encountered in most space-related applications (including exploration, tourism and defense fields) and represent a subject of growing interest in the…
