Spectral Modeling of Rotating Turbulent Flows
J. Baerenzung, P. D. Mininni, A. Pouquet +2
We test a subgrid-scale spectral model of rotating turbulent flows against direct numerical simulations. The particular case of Taylor-Green forcing at large scale is considered, a…
Helicity cascades in rotating turbulence
P. D. Mininni, A. Pouquet
The effect of helicity (velocity-vorticity correlations) is studied in direct numerical simulations of rotating turbulence down to Rossby numbers of 0.02. The results suggest that…
High-order low-storage explicit Runge-Kutta schemes for equations with quadratic nonlinearities
Marc E. Brachet, Pablo D. Mininni, Duane L. Rosenberg +1
We show in this paper that third- and fourth-order low storage Runge-Kutta algorithms can be built specifically for quadratic nonlinear operators, at the expense of roughly doublin…
The Lagrangian-averaged model for magnetohydrodynamics turbulence and the absence of bottleneck
Jonathan Pietarila Graham, Pablo D. Mininni, Annick Pouquet
We demonstrate that, for the case of quasi-equipartition between the velocity and the magnetic field, the Lagrangian-averaged magnetohydrodynamics alpha-model (LAMHD) reproduces we…
Generalized Eulerian-Lagrangian description of Navier-Stokes and resistive MHD dynamics
Carlos Cartes, Miguel D. Bustamante, Annick Pouquet +1
New generalized equations of motion for the Weber-Clebsch potentials that describe both the Navier-Stokes and MHD dynamics are derived. These depend on a new parameter, which has d…
Spectral Modeling of Magnetohydrodynamic Turbulent Flows
J. Baerenzung, H. Politano, Y. Ponty +1
We present a dynamical spectral model for Large Eddy Simulation of the incompressible magnetohydrodynamic (MHD) equations based on the Eddy Damped Quasi Normal Markovian approximat…
