Abstract

In this paper a procedure for large-eddy simulation (LES) has been devised for fluid and magnetohydrodynamic turbulence in Fourier space using the renormalized parameters. The parameters calculated using field theory have been taken from recent papers by Verma [Phys. Rev. E, 2001; Phys. Plasmas, 2001]. We have carried out LES on $6 4^{3}$ grid. These results match quite well with direct numerical simulations of $12 8^{3}$ . We show that proper choice of parameter is necessary in LES.
