Wall-Resolved Large-Eddy Simulation of a Three-Element High-Lift Airfoil

Wall-modeled large eddy simulation in complex geometries with application to high-lift devices

In large eddy simulations (LES) of wall-bounded flows, the need to resolve energycarrying eddies in the vicinity of the wall leads to a prohibitive cost which prevents its use at very high Reynolds numbers. To overcome this limitation, many attempts have been made in the last two decades to model the unresolved scales near the wall. These works mainly focused on two different approaches: hybrid...

Lesfoil: a European Project on Large Eddy Simulations around a High-lift Airfoil at High Reynolds Number

This paper presents work carried out in the LESFOIL project, which studies Large Eddy Simulations (LES) of the ow around high-lift airfoils, during its rst 24 months. The Reynolds number for the selected Aerospatiale A-airfoil is high (Re = 2:1 10 based on the freestream velocity and the chord length). If some kind of near-wall treatment could be used, the near-wall streaks would not be resolve...

Investigations of Three- Dimensional Turbulent Cavity Flow Using Large Eddy Simulation Approach

Canopy element influences on resolved- and subgrid-scale energy within a large-eddy simulation

Large-eddy simulations described here have included the effect of canopy drag through the depth of a plant canopy. Specifically, we have considered the simulation of flow through a forest. Drag forces enter the simulation with the inclusion of form and viscous drag forces in the momentum equation. In addition, we have carried a variable to represent the kinetic energy (KE) associated with the t...
