We are all set for the #APSDFD2024! Check out our exciting talks on #bubbles, #drops, #turbulence and some (brain juice) #cerebrospinal flows. @MaddyFederle @MRavisankar_ @brownengin

Wrapping up an amazing summer @brownengin with our UTRA and high school students! Excited to see all the great things they will achieve in their future endeavours.

Just out in @PhysRevLett! What floats up and breaks scaling laws on the way?🫧Bubble-induced turbulence gets a viscoelastic twist by @MRavisankar_ @brownengin Check this out: doi.org/10.1103/q7xk-1…
Using science to explain the everyday world, Brown researchers from Professor Roberto Zenit's lab used the physics of a special unreturnable shot in squash to further the science behind shock-dampening technologies of mechanical systems. brown.edu/news/2025-06-1…
Huge congrats to the newest PhD from our lab, Dr. @MRavisankar_, on defending his dissertation @brownengin: “Bubbly flows in non-Newtonian fluids and viscous Newtonian fluids.” He’s now a master of all things bubbly and sticky. Next stop: Postdoc at @UniOslo! 🎉 Proud of you!

Just out in PNAS @PNASNews: The physics behind squash’s most satisfying shot—the nick. When hit just right, the ball rolls out with no bounce, "no mercy". A beautiful blend of precision and mechanics. The work was led by @MRavisankar_ @brownengin pnas.org/doi/10.1073/pn…
Unfortunately couldn't make it to ICMF in Toulouse this year, but proud to share that my student @MaddyFederle presented her exciting work on bubble emulsions in microgravity @brownengin. Great to see the next generation pushing boundaries! 🚀🫧 #ICMF2025 #FluidDynamics

The 2025 ENGN 0350/1350 Art Fluids Exhibition @brownengin was a fantastic success! Fountains of light and chocolate, an engineered Eden, campus wind tunnels, and more! Proud of my students for their creativity and hard work! #ArtFluids
A new paper, by Professor Roberto Zenit (@ZenitLab), has been published in the latest issue of @APSphysics Reviews of Modern Physics. Read more: journals.aps.org/rmp/abstract/1…
I am very happy to share that our paper on ‘Gas bubble dynamics’ is finally published in Reviews of Modern Physics @APSphysics. It was a great pleasure to write it with my friend and long-time collaborator Dominique Legendre. Happy bubble-reading! doi.org/10.1103/RevMod…
This week, @MaddyFederle and I got to test our homogeneous isotropic turbulence chamber in microgravity at @NASAglenn! During the drop, the experiment experiences 2.2 seconds of microgravity, allowing us to study multiphase flows in microgravity. Stay tuned for more🫧 @brownengin


We know that cuts to federal science agencies are creating hardships for our members. That’s why we’re offering no-cost membership renewal for current members impacted. It’s just one of our efforts to support the #physics community. Learn how you can get involved:…
Excited to share this journal article, which is the PhD work of Andres Zambrano, a former member of our lab! Check it out!
How do microorganisms propel themselves through fluid with suspended particles? Théry et al (go.aps.org/4hg8AWO) use theory and experiments to show that more particles can help increase thrust relative to drag, though it depends on the geometry of the helical tail.
Had a lot of fun teaching physics to some brilliant young minds @SquashBusters. Who says professors can't handle teenagers? (Spoiler: they ask tougher questions than my grad students.) @brownengin
Another day @brownengin where students compete to maximize drag on badminton shuttles launched from a large air gun. The real challenge? Taking down the reigning champ—me (course tee, cool sunglasses, you know the drill 😎).



Explore the mesmerizing world of #FluidDynamics with @fyfluiddynamicson on high-speed photography, like the “Milk-Drop Coronet.” Modern recreations by @BrownUniversity students from Roberto Zenit's lab, highlight the beauty of #droplet impacts. @PhDVoice @PostdocVoice
Time for some Arts and Fluids! Kudos to the organisers of #BIFD2024 in #Edinburgh.
Prof. Roberto Zenit (Brown) speaking about the fluid mechanics of artistic painting at #BIFD2024 in #Edinburgh.
Congratulations to Dr. Andres Zambrano on successfully defending his PhD dissertation, 'On the Locomotion of Rigid and Flexible Helical Swimmers in Dilute Suspensions at Low Reynolds Number' @brownengin. He will be joining @prattandwhitney as a Senior Research Engineer. Proud!

Please submit your abstract or register before 8:00 a.m., Wednesday, June 19th. For the soundbites, all topics on active research are welcome, at any stage of maturity. This meeting is possible thanks to the generous support of @brownengin, @brown_physics, and @ApsDsoft.
Jay Tang and I are hosting the next installment of New England Complex Fluids workshop @BrownUniversity Friday 6/21. Please consider attending and presenting a soundbite! More info: complexfluids.org/necf/index.php Registration in advance is required (free).
