The dispersion of a passive scalar downstream of a wall-mounted cube is examined using
direct numerical simulations and turbulence models applied to the Reynolds equations. The …

We present a numerical study of scalar transport released from a line source downstream of
a square obstacle to investigate the capabilities and limitations of gradient-transport …

The diffusion of a plume of dye in uniformly sheared turbulent flow in a water tunnel was
investigated using simultaneous stereoscopic particle image velocimetry (SPIV) and planar …

Digital in-line holography is applied to studying the trajectories of individual water droplets in
airflow. In order to track the particles, multiple exposure holography is performed using a …

The motivation for the present work comes from the fact that a few recent publications
describing separation flows report a counter-gradient diffusion phenomenon (CDP) along …

Diamond is a nearly ideal material for detecting ionising radiation. Its outstanding radiation
hardness, fast charge collection and low leakage current allow it to be used in high radiation …

The transport of momentum and a passive scalar (temperature) in a three-dimensional
transitional wake of a heated square cylinder has been carried out through direct numerical …

Ce travail expérimental concerne la diffusion de la chaleur en aval d'une source ponctuelle
placée au culot d'un corps d'Ahmed. Trois géométries particulières ont été étudiées avec …

A Lagrangian study of the statistical properties of the orientation of a passive scalar gradient
is performed using experimental data and a simple, numerical analysis. It is shown that, in a …

Abstract The expansion of High Performance Computing (HPC) capabilities is allowing
Computational Fluid Dynamics (CFD) methods to be applied to model dispersion in urban …
