▪ Abstract I have sometimes thought that what makes a man's work classic is often just this
multiplicity [of interpretations], which invites and at the same time resists our craving for a …

▪ 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 preface begins' Turbulence is a dangerous topic...'—with which any aircraft operator will
agree—but goes on'... which is often at the origin of serious fights in the scientific meetings …

The alignment between vorticity and eigenvectors of the strain‐rate tensor in numerical
solutions of Navier–Stokes turbulence is studied. Solutions for isotropic flow and …

We study the statistics of an ensemble of images taken in the woods. Distributions of local
quantities such as contrast are scale invariant and have nearly exponential tails. Power …

This paper deals with the probability density function (PDF) of velocity differences between
two points separated by distance r. Measurements of PDFs were made, for r lying in the …

All objects considered previously have been identified by specifying that some measure
distributed on them is uniform: For example, the concentration on an isoconcentration …

This review addresses a central question in the field of complex systems: given a fluctuating
(in time or space), sequentially measured set of experimental data, how should one analyze …

Several simple mathematical models for the turbulent diffusion of a passive scalar field are
developed here with an emphasis on the symbiotic interaction between rigorous …
