Information-Preserving SGS model based on the local inter-scale equilibrium hypothesis
Takeru Hashimoto, Takahiro Tsukahara, Ryo Araki
Large eddy simulation has been widely used to simulate turbulence at balanced computational cost and accuracy. Many Subgrid-Scale (SGS) models have been proposed over the years, wh…

Scale-to-Scale Information Flow Amplifies Turbulent Fluctuations
Tomohiro Tanogami, Ryo Araki
In three-dimensional turbulence, information of turbulent fluctuations at large scales is propagated to small scales. Here, we investigate the relation between the information flow…
