“Turbulence”

Nicole Sharp - February 3, 2023January 10, 2023

In his recent short film, artist Roman De Giuli explores turbulence using metallic paints and inks in a fishtank. The effects are beautiful: sparkling pigments dispersing in clouds, mushroom- and Keep reading

Turbulence From Vortex Rings

Nicole Sharp - January 4, 2023December 1, 2022

When vortex rings collide, they reconnect into smaller, rings that eventually break down into chaos. Here, researchers experiment with colliding multiple vortex rings — focusing on an eight-ring collision. When Keep reading

Turbulence in Accretion Disks

Nicole Sharp - November 3, 2022October 12, 2022

Accretion disks form everywhere, from around young, planet-building stars to massive black holes. As matter circles in the disk, it slowly loses angular momentum and falls inward toward the central Keep reading

Rising Through Turbulence

Nicole Sharp - October 18, 2022September 27, 2022

Plankton — microscopic creatures with often limited swimming abilities — can face daily journeys of hundreds of vertical meters in the ocean. That’s a daunting prospect for any tiny swimmer. Keep reading

Bubbles in Turbulence

Nicole Sharp - August 9, 2022July 28, 2022

In nature and industry, swarms of bubbles* often encounter turbulence in their surrounding fluid. To study this situation, researchers used numerical simulation to observe bubbles across a range of density, Keep reading

Using Turbulence in Flight

Nicole Sharp - May 12, 2022April 28, 2022

When small, heavy particles are in a turbulent flow, they settle faster than in a quiescent one. Their interactions with turbulent eddies sweep them along, extracting energy that lengthens their Keep reading

Turbulence in Flight

Nicole Sharp - March 14, 2022February 23, 2022

Eagles and other birds spend much of their lives in the turbulence of our atmospheric boundary layer. Some of their interactions with turbulence — like using topographical effects to aid Keep reading

Elastic Turbulence

Nicole Sharp - January 26, 2022January 11, 2022

Decades ago, engineers pumping polymer-filled drilling liquids into porous rock noticed sudden and dramatic increases in the viscosity of the liquid. Within the tiny pores of the rock, conventional (i.e., Keep reading
