Modeling the pressure Hessian and viscous Laplacian in Turbulence: comparisons with DNS and implications on velocity gradient dynamics
L. Chevillard, C. Meneveau, L. Biferale +1
Modeling the velocity gradient tensor A along Lagrangian trajectories in turbulent flow requires closures for the pressure Hessian and viscous Laplacian of A. Based on an Eulerian-…
Matrix Exponential-Based Closures for the Turbulent Subgrid-Scale Stress Tensor
Yi Li, Laurent Chevillard, Gregory Eyink +1
Two approaches for closing the turbulence subgrid-scale stress tensor in terms of matrix exponentials are introduced and compared. The first approach is based on a formal solution…
Intermittency and universality in a Lagrangian model of velocity gradients in three-dimensional turbulence
Laurent Chevillard, Charles Meneveau
The universality of intermittency in hydrodynamic turbulence is considered based on a recent model for the velocity gradient tensor evolution. Three possible versions of the model…
