Mixing Leidenfrost Drops
When placed on a very hot, patterned surface, droplets will self-propel on a layer of their own vapor. Here, researchers use this to drive droplets to coalesce so that they Keep reading
“Otherworld, Vol. 1”
Roman De Giuli’s “Otherworld, Volume 1” is a beautiful exploration of color and flow. Glittery particulates act as tracers in the flow, reminiscent of the way rheoscopic fluids do. In Keep reading
“Unity”
Rus Khasanov’s latest short film, “Unity,” is all about coming together with droplets coalescing, globules bursting, and colors mixing. Take a glittery, paint-filled break and enjoy some macro-filmed fluid dynamics Keep reading
Inside a Heart
You may not give it much thought, but there is important fluid dynamics happening inside you every moment of every day, especially inside your heart. Of the four chambers of Keep reading
A Golden Swirl
As much as I love exploring flashy examples of fluid dynamics, like shock waves around aircraft or what happens when non-Newtonain fluids get crushed by a hydraulic press, my favorite moments Keep reading
Blackwater Rivers
Blackwater rivers, like the Suwannee River in Florida, carry waters so laden with organic material that they’re dyed a deep, dark brown. For the Suwannee, most of this material comes Keep reading
A Splat is Born
View this post on Instagram You BLOW my mind! 💀💣 When I did my first water droplet video, I didn't think that it would become a trend in the hand Keep reading
Bioinspiration, Underwater Sniffing, and Mixing Toothpaste
In this month’s FYFD/JFM video, we explore some intersections between the animal kingdom and our own lives. Learn about designing better buildings with inspiration from termites; see the fascinating superpower Keep reading
Foam and Flow
Fluid dynamics often play out on a scale that’s difficult to appreciate from our earthbound perspective, but fortunately, we have tools to aid us. This natural-color satellite image shows Rupert Keep reading
