Research news on Turbulence

Turbulence as a research area investigates the physics, modeling, and prediction of highly irregular, vortical fluid motion characterized by strong nonlinearity, multiscale interactions, and enhanced mixing and dissipation. It encompasses theoretical analysis of the Navier–Stokes equations, development of turbulence closures and reduced-order models, and statistical descriptions such as energy spectra and intermittency. The field spans direct numerical simulations, large-eddy and Reynolds-averaged approaches, and experimental diagnostics to study transition to turbulence, coherent structures, and cascade processes in gases and liquids, with applications ranging from aerodynamics and geophysical and astrophysical flows to engineering systems, combustion, and environmental fluid mechanics.

Data-driven model captures dynamics of turbulence at scale

Whether the dust borne on the violent winds of a tornado or the sugar grains in a swirled cup of coffee, the behavior of particles carried along in turbulence is subject to some similarities—all of them difficult to predict ...

Why dolphins swim so fast: The secrets of hidden whirlpools

Dolphins are famous for their speed and agility in the water, but what exactly allows them to swim so effectively? Scientists have been asking this question for years, hoping to learn how to optimize propulsion in fluids ...

Clearing the path for turbulence-free quantum communication

A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric turbulence, one of the main causes of distortion and errors when sending quantum information through ...
