▪ Abstract This article reviews the transport properties of coherent vortices in rotating
barotropic flows. It is shown that vortices induce regular Lagrangian motion inside their …

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 …

We introduce a Lagrangian definition for the boundaries of coherent structures in two-
dimensional turbulence. The boundaries are defined as material lines that are linearly stable …

The structure of premixed turbulent flames is a problem of fundamental interest in
combustion theory. Possible flame geometries have been imagined and diagrams indicating …

One-dimensional advection of sharp and smooth passive scalar profiles.(Left) Top pattern
labeled t= 0 shows three different initial conditions. Only approximately one-third of the …

A solution of decaying two-dimensional turbulence at large Reynolds number is analysed by
means of an automated vortex census. The census identifies the flow structures which …

Freely evolving two-dimensional turbulence is dominated by coherent vortices. The density
of these vortices decays in time as ρ∼ t− ξ with ξ≊ 0.75. A new scaling theory is proposed …

Results from a wide range of direct numerical simulations of forced-dissipative, differentially
rotating two-dimensional turbulence are presented, in order to delineate the broad …

The formation, growth, and transport of soot is investigated via large scale numerical
simulation in a three-dimensional turbulent non-premixed n-heptane/air jet flame at a jet …

We discuss a series of numerical experiments on the dispersion of neutrally buoyant
particles in two-dimensional turbulent flows. The topology of two-dimensional turbulence is …
