▪ 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 …

Most of the current Eulerian vortex identification criteria, including the Q criterion and the λ ci
criterion, are exclusively determined by the eigenvalues of the velocity gradient tensor or the …

The objective of this paper is to complement previous reviews focusing on somewhat more
classical aspects of mixing in the content of chemical reaction engineering and to provide …

This paper argues that the active turbulence and coherent motions near the top of a
vegetation canopy are patterned on a plane mixing layer, because of instabilities associated …

Turbulent flow over a backward-facing step is studied by direct numerical solution of the
Navier–Stokes equations. The simulation was conducted at a Reynolds number of 5100 …

Providing a comprehensive grounding in the subject of turbulence, Statistical Theory and
Modeling for Turbulent Flows develops both the physical insight and the mathematical …

Studying the microclimate of plant canopies has long motivated scientists in various
research fields such as agronomy, ecology or silviculture, and almost a century has passed …

We analyse the currently popular vortex identification criteria that are based on point-wise
analysis of the velocity gradient tensor. A new measure of spiralling compactness of material …

To date, flow through submerged aquatic vegetation has largely been viewed as perturbed
boundary layer flow, with vegetative drag treated as an extension of bed drag. However …

Direct numerical simulation of the incompressible Navier–Stokes equations is used to study
flows where laminar boundary-layer separation is followed by turbulent reattachment …
