Spectral Modeling of Rotating Turbulent Flows
Baerenzung, J., Mininni, P.D, Pouquet, A., Politano, H. and Ponty, Y.
A subgrid-scale spectral model of rotating turbulent flows is tested against direct numerical simulations (DNSs). The case of Taylor–Green forcing is considered, a configuration that (...) Read the whole article

Spectral modeling of magnetohydrodynamic turbulent flows
Baerenzung, J., Politano, H., Ponty, Y. and Pouquet, A.
We present a dynamical spectral model for large-eddy simulation of the incompressible magnetohydrodynamic (MHD) equations based on the eddy damped quasinormal Markovian approximation. (...) Read the whole article

Hyperviscosity, Galerkin Truncation, and Bottlenecks in Turbulence
Frisch, U., Kurien, S., Pandit, R., Pauls, W., Ray, S.S., Wirth, A. and Zhu, J.Z
It is shown that the use of a high power α of the Laplacian in the dissipative term of hydrodynamical equations leads asymptotically to truncated inviscid conservative dynamics (...) Read the whole article

Entire solutions of hydrodynamical equations with exponential dissipation
Bardos, C., Frisch, U., Pauls, W., Ray, S.S. and Titi, E.S.
Abstract: We consider amodification of the three-dimensional Navier–Stokes equations and other hydrodynamical evolution equations with space-periodic initial conditions in which the (...) Read the whole article
