DNS Channel Data Re_tau=10000 high moments
Description
This dataset contains the statistical moments based on the instantaneous velocities (H-moments) up to order 6 of a new Direct Numerical Simulation of a Poiseuille channel flow that has been conducted for a friction Reynolds number of 10000, using the pseudo-spectral code LISO.
