Subgrid Scale Modeling for Large Eddy Simulation of Buoyant Turbulent Flows
… measures of important quantities such as turbulence budgets, in a simplified flow configuration involving buoyancy effects on a turbulent flow.</p> <p>Three existing LES SGS models for buoyant turbulent flows are assessed by performing LES and comparing the results to DNS data found in the …

Numerical methods for the unsteady incompressible Navier-Stokes equations and their application to the Direct Numerical Simulation of turbulent flows
… accuracy of the modeled expressions in the k-e turbulence model. Using the results of the DNS, the terms in the exact and modeled k-e equations are computed. These terms are examined to see where the models fail for these flows. DNS budgets for k and dissipation in a film cooling jet flow are …

Reducing turbulence- and transition-driven uncertainty in aerothermodynamic heating predictions for blunt-bodied reentry vehicles
… by Topalian et al. A first study aimed to reduce turbulence-driven heating prediction uncertainty by providing high-quality data suitable for calibrating Reynolds-averaged Navier--Stokes turbulence models to address the atypical boundary layer characteristics found in such reentry problems. The …
