A new hybrid mass-flux/ high-order turbulence closure for ocean vertical mixing
Amrapalli Garanaik, Filipe Pereira, Katherine Smith +4
While various parameterizations of vertical turbulent fluxes at different levels of complexity have been proposed, each has its own limitations. For example, simple first-order clo…
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…
Challenges in Modelling and Simulation of Turbulent Flows with Spatially-Developing Coherent Structures
F. S. Pereira, L. Eca, G. Vaz +1
The objective of this work is to investigate the challenges encountered in Scale-Resolving Simulations (SRS's) of turbulent wake flows driven by spatially-developing coherent struc…
