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…
Verification and Validation: the Path to Predictive Scale-Resolving Simulations of Turbulence
F. S. Pereira, F. F. Grinstein, D. M. Israel +1
This work investigates the importance of verification and validation (V&V) to achieve predictive scale-resolving simulations (SRS) of turbulence, i.e., computations capable of reso…
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…
Modeling and Simulation of Transitional Taylor-Green Vortex Flow with PANS
Filipe S. Pereira, Fernando Grinstein, Daniel M. Israel +2
The PANS equations model is used to predict the transitional Taylor-Green vortex (TGV) flow at Re=3000. A new form of the closure is proposed, in which the PANS procedure is applie…
Effects of Initial Condition Spectral Content on Shock Driven Turbulent Mixing
Nicholas J. Nelson, Fernando F. Grinstein
The mixing of materials due to the Richtmyer-Meshkov instability and the ensuing turbulent behavior is of intense interest in a variety of physical systems including inertial confi…
