Coarse-graining two-dimensional turbulence via dynamical optimization
Bruce Turkington, Qian-Yong Chen, Simon Thalabard
A model reduction technique based on an optimization principle is employed to coarse-grain inviscid, incompressible fluid dynamics in two dimensions. In this reduction the spectral…
Optimal thermalization in a shell model of homogeneous turbulence
Simon Thalabard, Bruce Turkington
We investigate the turbulence-induced dissipation of the large scales in a statistically homogeneous flow using an "optimal closure," which one of us (BT) has recently exposed in t…
A statistical mechanics framework for the large-scale structure of turbulent von K{á}rm{á}n flows
Simon Thalabard, Brice Saint-Michel, Éric Herbert +2
In the present paper, recent experimental results on large scale coherent steady states observed in experimental von K{á}rm{á}n flows are revisited from a statistical mechanics per…
Anomalous spectral laws in differential models of turbulence
Simon Thalabard, Sergey Nazarenko, Sebastien Galtier +1
Differential models for hydrodynamic, passive-scalar and wave turbulence given by nonlinear first- and second-order evolution equations for the energy spectrum in the -space wer…
