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…
