DNS data of the turbulent round jet flow at Re=3500

This item contains the mean flow, turbulent intensities, Reynolds stress, turbulent budgets and the probability density function of the axial velocity of a DNS of a spatially evolving turbulent round jet flow at a Reynolds number of 3500 based on the orifice diameter and the bulk velocity at the orifice.
