Modeling and Simulation of Transitional Rayleigh-Taylor Flow with Partially-Averaged Navier-Stokes Equations
Filipe S. Pereira, Fernando F. Grinstein, Daniel M. Israel +2
The partially-averaged Navier-Stokes (PANS) equations are used to predict the variable-density Rayleigh-Taylor (RT) flow at Atwood number 0.5 and maximum Reynolds number . Thi…
Partially-Averaged Navier-Stokes Simulations of Turbulence Within a High-Order Flux Reconstruction Framework
Tarik Dzanic, Sharath Girimaji, Freddie Witherden
High-order methods and hybrid turbulence models have independently shown promise as means of decreasing the computational cost of scale-resolving simulations. The objective of this…
Partially-Averaged Navier-Stokes Closure Modeling for Variable-Density Turbulent Flow
F. S. Pereira, F. F. Grinstein, D. M. Israel +2
This work extends the framework of the partially-averaged Navier-Stokes (PANS) equations to variable-density flow, \text{i.e.}, multi-material and/or compressible mixing problems w…
Turbulence closure modeling with data-driven techniques: Investigation of generalizable deep neural networks
Salar Taghizadeh, Freddie Witherden, Yassin Hassan +1
Generalizability of machine-learning (ML) based turbulence closures to accurately predict unseen practical flows remains an important challenge. At the Reynolds-averaged Navier-Sto…
