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. 🔗 journals.aps.org/prfluids/abs... #FluidDynamics #DropletGeneration

One AI policy for every lab? Probably the wrong starting point. A new framework maps four research cultures to different uses of AI, from coding and data analysis to reproducibility and data privacy. 🔗 www.nature.com/articles/d41... #Research #AIinScience #OpenScience

📅 From Oct. 26–30, we'll be attending the Journées de la Matière Condensée #JMC2026, one of the major French conferences in #CondensedMatterPhysics. More info: www.LeidenForce.eu/Conferences #Research #PhDLife #Physics #PhaseChange

Water 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? 🔗 shorturl.at/gk6KO #FluidDynamics

The #NavierStokes equations describe how fluids flow, from ocean currents to blood in our veins, and they've resisted a full solution for over 150 years. This summer, #AI cracked one class of these equations in record time, sparking real debate in the #FluidMechanics community 🔗 shorturl.at/L50O5

When #AI can produce a convincing answer in seconds, teaching cannot be reduced to finding information. Students also need to learn how to check, question and #challenge what they are given, especially when the answer sounds right but isn’t. 🔗 theconversation.com/quest-ce-quu... #Education

What 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. 🔗 phys.org/news/2026-08... #FluidDynamics #Hydrology #UrbanWater

Keeping hydrogen liquid for 9 days means keeping it near −253°C. In this aircraft, heat management becomes a flight-critical problem: evaporation, cryogenic storage and fuel-cell losses all have to be controlled. 🔗 www.science-et-vie.com/technos-et-f... #Hydrogen #Thermofluids #Cryogenics

What 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. 🔗 shorturl.at/Ce8nH #Geophysics #FluidDynamics #Geology

Starting a physics career is also about knowing yourself: theory or experiments? Academia or industry? Working alone or in a team? A useful guide for students and early-career researchers navigating these choices. 🔗 physicsworld.com/a/from-stude... #Physics #EarlyCareer #ScienceCareers

A 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. 🔗 pubs.aip.org/aip/pof/arti... #FluidDynamics #MultiphaseFlow #Physics

What 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. 🔗 pubs.aip.org/aip/pof/arti... #FluidDynamics #Droplets #Marangoni

How does the #LeidenfrostEffect work on an immersed wire? 🎥 youtu.be/IXXteFzvyqM?... New experimental footage by PhD student Lorena V. García, at Institut Lumière Matière, UnivLyon1 as part of the #LeidenForce Doctoral Network (MSCA, #HorizonEurope). #Physics #FluidDynamics #HighSpeedVideo

How 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. 🔗 journals.aps.org/prfluids/abs... #FluidDynamics #Droplets #InterfacialPhysics

A droplet’s shape can determine where it travels. As a buoyant droplet deforms in a microchannel, the resulting hydrodynamic lift can oppose buoyancy and move it toward the channel center. Larger droplets experience stronger centering forces. 🔗 shorturl.at/XJce4 #FluidMechanics #Microfluidics

How do you build an experiment when no off-the-shelf tool quite fits? #3DPrinting lets researchers design & make their own experimental hardware. For #FluidExperiments, that can mean custom flow cells and reactors tailored to a specific #setup. 🔗 www.nature.com/articles/d41... #FluidDynamics

What if #AI helped us engage more with the real world, instead of replacing it? Daniel Barcay argues that good AI design should leave space for human relationships, judgment & action. A useful question as AI enters more areas of #research and daily life. 🔗 usbeketrica.com/fr/article/i... #Science

When a drop hits a viscous liquid film, its kinetic energy can go into spreading, penetrating the film or bouncing back. Changing the density ratio shifts this balance, revealing new regimes of impact dynamics. 🔗 doi.org/10.1063/5.03... #FluidDynamics #DropImpact #InterfacialFlows

🎥 After the video on #NavierStokes we recently shared, Quanta Magazine revisits the debate: an OpenAI #AI system claims to have solved a variant of the finite-time "blow-up" problem. Useful reminder: #turbulence itself remains largely misunderstood. 🔗 youtu.be/PsWR1rQEWYo?... #LeidenForce #Physics

Heat is not always as fast as we assume. A model with two characteristic response times shows that this can matter for fluid motion: depending on their relative importance, thermal convection may remain steady or develop oscillations. 🔗 pubs.aip.org/aip/pof/arti... #HeatTransfer #FluidDynamics

The #NavierStokes equation has been getting a lot of attention lately. If you want to take a closer look at what lies behind its different terms, here’s a short video by Lorelscience breaking down the forces at play. youtube.com/shorts/6uHjH... #FluidMechanics #FluidDynamics #HeatTransfer #Physics

Every droplet hides a full world of physics. #Droplets #Science #Physics #Research #LeidenfrostEffect #LeidenLog

What happens when two droplets collide? It depends on whether they can mix. Droplets made of liquids that mix stop oscillating faster, while droplets that stay separate keep moving for longer. 🔗 pubs.aip.org/aip/pof/arti... #FluidDynamics #DropletDynamics

How can a chemical reaction make a liquid surface oscillate? When 2 reactants meet, they change the #SurfaceTension & create a #Marangoni flow. This motion can become oscillatory, revealing the close link between chemical reactions & #FluidDynamics. 🔗 pubs.aip.org/aip/pof/arti... #InterfacialFlows

A subtle change in wall temperature can reshape flow in a microchannel. For a #hydrogen Knudsen pump, a #temperature profile with a colder region inside the channel generates a stronger pressure drop and increases the predicted #transport capacity by 9.6%. 🔗 pubs.aip.org/aip/pof/arti...

What should a publication in #FluidMechanics contribute to? #PhysicsOfFluids is evolving its positioning around a simple principle: “Physics First”, placing the advancement of knowledge in #physics at the heart of its editorial policy. 🔗 shorturl.at/3TawU

Charged water #droplets can start moving spontaneously as they evaporate on a dry surface. The effect appears when the droplet becomes very small and strongly pinned, revealing a surprising link between #Evaporation, #ElectricCharge and contact-line dynamics. 🔗 shorturl.at/LIILg #FluidDynamics

How can scientific knowledge become more accessible while keeping research publishing sustainable? Different #OpenAccess models offer different answers. Diamond Open Access is one approach, with neither authors nor readers paying publication or access fees. 🔗 phys.org/news/2026-07... #OpenScience

Understanding an eruption means linking what we see at the surface to processes occurring deeper underground. A useful reminder that complex fluid phenomena often require multiple scales of observation. 🔗 www.radiofrance.fr/franceinter/... #Volcanology #Geophysics #FluidDynamics
