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…
Scale interactions and scaling laws in rotating flows at moderate Rossby numbers and large Reynolds numbers
P. D. Mininni, A. Alexakis, A. Pouquet
The effect of rotation is considered to become important when the Rossby number is sufficiently small, as is the case in many geophysical and astrophysical flows. Here we present d…
A paradigmatic flow for small-scale magnetohydrodynamics: properties of the ideal case and the collision of current sheets
E. Lee, M. E. Brachet, A. Pouquet +2
We propose two sets of initial conditions for magnetohydrodynamics (MHD) in which both the velocity and the magnetic fields have spatial symmetries that are preserved by the dynami…
