▪ Abstract We review the direct numerical simulation (DNS) of turbulent flows. We stress that
DNS is a research tool, and not a brute-force solution to the Navier-Stokes equations for …

Abstract Particle Tracking Velocimetry (PTV) is a well-known technique for the determination
of velocity vectors within an observation volume. However, for a long time it has rarely been …

The mean flow and turbulent statistics obtained from the numerical simulation of the fully
