Since the seminal studies by Osborne Reynolds in the nineteenth century, pipe flow has
served as a primary prototype for investigating the transition to turbulence in wall-bounded …

The breakup of drops and bubbles in turbulent fluids is a key mechanism in many
environmental and engineering processes. Even in the well-studied dilute case, quantitative …

Fluid flows between rotating concentric cylinders exhibit two distinct routes to turbulence. In
flows dominated by inner-cylinder rotation, a sequence of linear instabilities leads to …

Transitional localized turbulence in shear flows is known to either decay to an absorbing
laminar state or to proliferate via splitting. The average passage times from one state to the …

In many geophysical and astrophysical flows, suppression of fluctuations along one
direction of the flow drives a quasi-two-dimensional upscale flux of kinetic energy, leading to …

Two-dimensional horizontally periodic Rayleigh–Bénard convection between stress-free
boundaries displays two distinct types of states, depending on the initial conditions. Roll …

It may come as a surprise that a phenomenon as ubiquitous and prominent as the transition
from laminar to turbulent flow has resisted combined efforts by physicists, engineers and …

We study the dynamics of a fixed wing at stall in a wind tunnel by measuring the
aerodynamic forces. We report experimental evidence of a critical Reynolds number from …

The mean azimuthal flow of puff, a key structure of the subcritical transition in pipe flow, is
studied numerically and theoretically in this Letter. It is revealed that the mean azimuthal …

Extreme events in turbulent flows are in general linked with sudden changes in the
dynamics of the system. Despite the increasing interest in modelling these events, their …
