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…
Depletion of Nonlinearity in Magnetohydrodynamic Turbulence: Insights from Analysis and Simulations
J. D. Gibbon, A. Gupta, G. Krstulovic +6
We build on recent developments in the study of fluid turbulence [Gibbon \textit{et al.} Nonlinearity 27, 2605 (2014)] to define suitably scaled, order- moments, , of…
Modeling of anisotropic turbulent flows with either magnetic fields or imposed rotation
A. Pouquet, J. Baerenzung, J. Pietarila Graham +3
We present two models for turbulent flows with periodic boundary conditions and with either rotation, or a magnetic field in the magnetohydrodynamics (MHD) limit. One model, based…
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…
Development of Anisotropy in Incompressible Magnetohydrodynamic Turbulence
Barbara Bigot, Sebastien Galtier, Helene Politano
We present a set of three-dimensional (3D) direct numerical simulations of incompressible decaying magnetohydrodynamic turbulence in which we investigate the influence of an extern…
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…
