To verify Large Eddy Simulation (LES) analysis for large scale structures in high-Reynolds number (Re), the LES based on the pseudo-spectral method were adapted for the turbulent channel flow in Re based on the friction velocity and the channel half-width 2000. Total grid numbers of the present LES were a one-eightieth of those of Direct Numerical Simulation (DNS). Compared with DNS database in the same Re condition, results of pre-multiplied spectra and quadrant analysis for large scale structure were quantitatively fitted with each other, except for the contribution of Reynolds stress in inner layer.
