The dispersion and mixing of passive scalar (temperature) fluctuations is studied in a
turbulent jet. The temperature fluctuations were produced by heated fine wire rings placed …

We review the efforts made by the scientific community in more than seventy years to
elucidate the behaviour of concentration fluctuations arising from localized atmospheric …

A meandering plume model that explicitly incorporatesinternal fluctuations has been
developed and used to model the evolutionof concentration fluctuations in point-source …

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 …

Measurements of concentration fluctuation profiles were made in a plume of saline tracer
from a ground level source in a water channel simulation of a neutrally stable rpugh surface …

Chatwin & Sullivan (1990) have demonstrated that, for a wide range of self-similar scalar
fields, the moments of the probability density function of concentration have a very simple …

The mixing of a scalar (temperature) emitted from a concentrated line source in fully
developed high-aspect-ratio turbulent channel flow is studied. The motivation for the work is …

This study is an experimental investigation of the probability density function (pdf) and the
fine structure of temperature fluctuations in uniformly sheared turbulence with a passively …

The present work aims at developing a spectral model for a passive scalar field and its
associated scalar flux in homogeneous anisotropic turbulence. This is achieved using the …

We experimentally investigate dispersion from a heated line source placed in the central
region of a turbulence mixing layer. Recently described by Veeravalli & Warhaft (1989) the …
