How do you produce a single droplet on the surface of a liquid bath?
Stretch a liquid filament with a spring-loaded probe. Stretch it too far, and it breaks into multiple drops; not far enough & no drop forms.

@denys-dutykh.comCan a solitary wave cross a patch of rotating liquid and emerge unchanged? With Matthew Hunt we studied waves on a conducting liquid under an electric field, when the liquid carries vorticity. Mathematical Methods in the Applied Sciences, 2026 (@wiley.com) 🧵 #FluidDynamics

@leidenforce.bsky.socialWater is usually the shield against #corrosion.
Here, charged droplets break down the shield itself: a Teflon #coating develops damage, exposing the copper beneath.
How should future protective surfaces respond to charged water?
@philosophicalmag.bsky.socialEver watched a flock of birds fly across the sky and wondered how they coordinate without colliding?
Turns out, they might not be thinking about it —they're just riding the air currents and letting #physics do the heavy-lifting: spr.ly/63321BGQJYR

@denys-dutykh.comFeynman called water waves “the worst possible example” of waves: “they have all the complications that waves can have.” With Didier Clamond and Dimitrios Mitsotakis, we wrote an open-access monograph on modelling them with variational principles (IAHR, 2024). 🧵 #FluidDynamics

@leidenforce.bsky.socialWhat if buried streams could become part of a city's flood-management system?
"Daylighting" urban streams can restore natural flow paths while creating space for water, habitats and people.
@leidenforce.bsky.socialWhat can bubbles in a hot spring tell us about the deep Earth?
In Zambia, helium isotopes in geothermal fluids reveal a connection between surface waters and the mantle, pointing to an early stage of continental rifting.

@m2oswimalliance.bsky.socialLet's dive into some wave talk.
#Fluiddynamics
@leidenforce.bsky.socialA bubble’s wake leaves a measurable signature on a nearby #droplet.
#HighSpeedImaging combined with a hydrodynamic model captures the droplet’s motion & deformation, linking what we see at the interface to the flow around it.
@leidenforce.bsky.socialWhat happens inside a drop as it dries?
As water evaporates, differences in surface tension can make the liquid circulate. Adding a surfactant changes this hidden motion and, in turn, the way the drop evaporates.
@leidenforce.bsky.socialHow does the #LeidenfrostEffect work on an immersed wire?
New experimental footage by PhD student Lorena V. García, at Institut Lumière Matière, UnivLyon1 as part of the #LeidenForce Doctoral Network (MSCA, #HorizonEurope).
@sohkamyung.bsky.social"The faster the insects wriggle, the more the fluid resists, courtesy of long strings of sugars it contains.
After years of study, scientists are still learning new things about how Raffles’ pitcher plants weaponize this strange fluid."
@leidenforce.bsky.socialHow do you make one droplet, rather than none or several?
Stretching a liquid filament with a simple probe reveals three regimes. In between, a single droplet can be produced with controlled size and <5% variation.
