The topic of this article is a review of the approach to extract pressure fields from flow
velocity field data, typically obtained with particle image velocimetry (PIV), by combining the …

The understanding of fluid turbulence has considerably progressed in recent years. The
application of the methods of statistical mechanics to the description of the motion of fluid …

▪ Abstract Passive scalar behavior is important in turbulent mixing, combustion, and pollution
and provides impetus for the study of turbulence itself. The conceptual framework of the …

The Lagrangian description of turbulence is characterized by a unique conceptual simplicity
and by an immediate connection with the physics of dispersion and mixing. In this article, we …

▪ Abstract Turbulence is ubiquitous in atmospheric clouds, which have enormous turbulence
Reynolds numbers owing to the large range of spatial scales present. Indeed, the ratio of …

The motion of fluid particles as they are pushed along erratic trajectories by fluctuating
pressure gradients is fundamental to transport and mixing in turbulence. It is essential in …

We use silicon strip detectors (originally developed for the CLEO III high-energy particle
physics experiment) to measure fluid particle trajectories in turbulence with temporal …

In flows, material does not vanish, nor does new material appear. The velocity fields
therefore have to satisfy conservation of mass. This law is easiest to formulate for steady …

Ethanol electrooxidation was investigated at platinum based electrodes: Pt, Pt—Sn, Pt—Re
dispersed on a high surface area carbon powder. The atomic composition of the bimetallic …

This paper describes a non-intrusive technique for measuring the instantaneous spatial
pressure distribution over a sample area in a flow field. A four-exposure PIV system is used …
