Scaling laws and local enhancements of buoyancy flux in stratified turbulent flows
Gyeongseob Song, Fabio Feraco, Raffaele Marino +6
In the presence of stratification, turbulent flows exhibit intermittency not only at small scales but also at large scales, comparable to the mean flow, as observed in the atmosphe…

Helicity subgrid-scale models and their numerical validation
Nobumitsu Yokoi, Pablo D. Mininni, Annick Pouquet +2
Large-eddy simulations (LES) with an appropriate subgrid-scale (SGS) model provide a powerful tool for investigating real-world turbulence. The Smagorinsky model, one of the simple…

Intermittency assessed through a model of kurtosis-skewness relation in MHD in fast dynamo regimes
Yannick Ponty, Helene Politano, Annick Pouquet
Intermittency as it occurs in fast dynamos in the MHD framework is evaluated through the examination of relations between normalized moments at third order (skewness S) and fourth…
