Non-local interactions in hydrodynamic turbulence at high Reynolds numbers: the slow emergence of scaling laws
P. D. Mininni, A. Alexakis, A. Pouquet
We analyze the data stemming from a forced incompressible hydrodynamic simulation on a grid of 2048^3 regularly spaced points, with a Taylor Reynolds number of Re~1300. The forcing…
Three regularization models of the Navier-Stokes equations
J. Pietarila Graham, Darryl Holm, Pablo Mininni +1
We determine how the differences in the treatment of the subfilter-scale physics affect the properties of the flow for three closely related regularizations of Navier-Stokes. The c…
Highly turbulent solutions of LANS-alpha and their LES potential
J. Pietarila Graham, Darryl Holm, Pablo Mininni +1
We compute solutions of the Lagrangian-Averaged Navier-Stokes alpha-model (LANS) for significantly higher Reynolds numbers (up to Re 8300) than have previously been accomplished. T…
Adaptive mesh refinement with spectral accuracy for magnetohydrodynamics in two space dimensions
D. Rosenberg, A. Pouquet, P. D. Mininni
We examine the effect of accuracy of high-order spectral element methods, with or without adaptive mesh refinement (AMR), in the context of a classical configuration of magnetic re…
Inverse cascades and alpha-effect at low magnetic Prandtl number
P. D. Mininni
Dynamo action in a fully helical Beltrami (ABC) flow is studied using both direct numerical simulations and subgrid modeling. Sufficient scale separation is given in order to allow…
Hydrodynamic and magnetohydrodynamic computations inside a rotating sphere
P. D. Mininni, D. C. Montgomery, L. Turner
Numerical solutions of the incompressible magnetohydrodynamic (MHD) equations are reported for the interior of a rotating, perfectly-conducting, rigid spherical shell that is insul…
