Résumé : Pseudospectral large-eddy simulations (LES) of incompressible magnetohydrodynamic (MHD) turbulence are performed with a maximum of 643 collocation points. Different gradient-diffusion type subgrid models are evaluated. This is done by comparing the obtained LES results to reference data stemming from high-resolution direct numerical simulations of decaying MHD turbulence with up to 5123 spectral modes. A newly developed MHD subgrid model, based on the ideal cross-helicity invariant of MHD turbulence, is tested and observed to perform excellently well.
