Abstract

We consider the numerical simulation of homogeneous magnetohydrodynamic turbulence decay depending on magnetic Reynolds number based on large eddy simulation. To close magnetohydrodynamic equation system the modified dynamic model is used and calculated at each time steps. Depending on the different magnetic Reynolds number the variation of the kinetic and magnetic energies of turbulence with time, and depending on the time the micro- and macro-scale turbulence were obtained.
