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…
Discovery of Algebraic Reynolds-Stress Models Using Sparse Symbolic Regression
Martin Schmelzer, Richard P. Dwight, Paola Cinnella
** This article is published (open-access). ** A novel deterministic symbolic regression method SpaRTA (Sparse Regression of Turbulent Stress Anisotropy) is introduced to infer alg…
Quantification of Model Uncertainty in RANS Simulations: A Review
Heng Xiao, Paola Cinnella
In computational fluid dynamics simulations of industrial flows, models based on the Reynolds-averaged Navier--Stokes (RANS) equations are expected to play an important role in dec…
