Small scale structures in three-dimensional magnetohydrodynamic turbulence
P. D. Mininni, A. Pouquet, D. C. Montgomery
We investigate using direct numerical simulations with grids up to 1536^3 points, the rate at which small scales develop in a decaying three-dimensional MHD flow both for determini…
Large scale flow effects, energy transfer, and self-similarity on turbulence
P. D. Mininni, A. Alexakis, A. Pouquet
The effect of large scales on the statistics and dynamics of turbulent fluctuations is studied using data from high resolution direct numerical simulations. Three different kinds o…
Magnetohydrodynamic activity inside a sphere
P. D. Mininni, D. C. Montgomery
We present a computational method to solve the magnetohydrodynamic equations in spherical geometry. The technique is fully nonlinear and wholly spectral, and uses an expansion basi…
Dynamo action at low magnetic Prandtl numbers: mean flow vs. fully turbulent motion
Yannick Ponty, Pablo Mininni, Jean-François Pinton +2
We compute numerically the threshold for dynamo action in Taylor-Green swirling flows. Kinematic calculations, for which the flow field is fixed to its time averaged profile, are c…
