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 [1,2]. We have carried out LES
on 64$^3$ grid. These results match quite
well with direct numerical simulations of 128$^3$.
We show that proper choice of parameter
is necessary in LES.
Keywords. Turbulence; large-eddy simulations.
