Numerical studies towards practical large-eddy simulation
Jérôme Boudet, Joëlle Caro, L. Shao +1
Large-eddy simulation developments and validations are presented for an improved simulation of turbulent internal flows. Numerical methods are proposed according to two competing c…
Shear-Improved Smagorinsky Model for Large-Eddy Simulation of Wall-Bounded Turbulent Flows
E. Leveque, F. Toschi, L. Shao +1
A shear-improved Smagorinsky model is introduced based on recent results concerning shear effects in wall-bounded turbulence by Toschi et al. (2000). The Smagorinsky eddy-viscosity…
Unified Multifractal Description of Velocity Increments Statistics in Turbulence: Intermittency and Skewness
L. Chevillard, B. Castaing, E. Leveque +1
The phenomenology of velocity statistics in turbulent flows, up to now, relates to different models dealing with either signed or unsigned longitudinal velocity increments, with ei…
On the Rapid Increase of Intermittency in the Near-Dissipation Range of Fully Developed Turbulence
Laurent Chevillard, Bernard Castaing, Emmanuel Leveque
Intermittency, measured as log(F(r)/3), where F(r) is the flatness of velocity increments at scale r, is found to rapidly increase as viscous effects intensify, and eventually satu…
Lagrangian Velocity Statistics in Turbulent Flows: Effects of Dissipation
L. Chevillard, S. G. Roux, E. Leveque +3
We use the multifractal formalism to describe the effects of dissipation on Lagrangian velocity statistics in turbulent flows. We analyze high Reynolds number experiments and direc…
Long time correlations in Lagrangian dynamics: a key to intermittency in turbulence
N. Mordant, J. Delour, E. Leveque +2
New aspects of turbulence are uncovered if one considers flow motion from the perspective of a fluid particle (known as the Lagrangian approach) rather than in terms of a velocity…
