Understanding how turbulence leads to the enhanced irreversible transport of heat and
other scalars such as salt and pollutants in density-stratified fluids is a fundamental and …

Transitional–turbulent spots bridge the deterministic laminar state with the stochastic
turbulent state and affect the transition zone length in engineering flows. Turbulent spot …

Transition from laminar to turbulent flow drastically changes the mixing, transport, and drag
properties of fluids, yet when and how turbulence emerges is elusive even for simple flow …

Turbulence is one of the most frequently encountered non-equilibrium phenomena in
nature, yet characterizing the transition that gives rise to turbulence in basic shear flows has …

Written by a team of international experts, Extremes and Recurrence in Dynamical Systems
presents a unique point of view on the mathematical theory of extremes and on its …

Experiments and numerical simulations have shown that turbulence in transitional wall-
bounded shear flows frequently takes the form of long oblique bands if the domains are …

An imposed strong magnetic field suppresses turbulence and profoundly changes the
nature of the flow of an electrically conducting fluid. We consider this effect for the case of …

Direct numerical simulations of stably stratified, turbulent channel flow at low to moderate
Reynolds number have been performed using large computational boxes and considering a …

Directed percolation (DP) has recently emerged as a possible solution to the century old
puzzle surrounding the transition to turbulence. Multiple model studies reported DP …

We study the large-scale motions in turbulent plane Couette flows at moderate friction
Reynolds number up to length of the domain. The presence of these very long structures is …
