DNS of the Turbulent Flow Evolving in a Plane Channel from the Entry to the Fully Developed State

Abstract

Direct numerical simulation of the turbulent flow spatially developing in a plane channel is performed. The channel is long enough for the turbulence to achieve the statistically invariant state in space and time. Spatial evolution of statistical quantities and Reynolds stress budgets are calculated. Results are compared to the canonical flows consisting of the zero-pressure gradient turbulent boundary layer and of the periodical channel flow.
