Implementation of a roughness element to trip transition in large-eddy simulation
In aerodynamics, the laminar or turbulent regime of a boundary layer has a strong influence on friction or heat transfer. In practical applications, it is sometimes necessary to trip the transition to turbulen...

Towards practical large-eddy simulations of complex turbulent flows
Turbulence that occurs in nature, or in engineering flows, is usually not, even approximatively, homogeneous. There are frequent variations of the mean velocity with position. By explicating the scale-by-scale...

ANALYSES OF URANS AND LES CAPABILITIES TO PREDICT VORTEX SHEDDING FOR RODS AND TURBINES
The objective of this study is to evaluate the capability of codes to simulate vortex shedding that occurs at the trailing edge of turbine blades. Firstly, unsteady RANS simulations (various k — ω models) are pre...
