This fantastic music video by Kim Pimmel is a beautiful merger of art and fluid dynamics. Using household goods (and some slightly more exotic ferrofluid), the video shows how mesmerizing diffusion, buoyancy, Marangoni flow, and other fluid effects can be up close. It may also be the first time I’ve ever seen fluid dynamics–specifically bubbles–used as characters! Also be sure to check out some of his previous videos, many of which also feature cool fluid dynamics. (Video credit and submission: K. Pimmel)

“Heavy Metals”
Photographer Alberto Seveso’s “Heavy Metals” series builds on his previous works capturing fluid dynamics. By dropping mixtures of ink, liquids, and metallic powder through different fluids, he creates ethereal, billowing forms that turn the processes of diffusion and turbulent mixing into something one could almost touch. Be sure to check out the rest of the series and his online portfolio for more examples. (Photo credits: A. Seveso; via Colossal; submitted by jshoer and @catnogood)
Splashy Heroines
In his latest work, photographer Jaroslav Wieczorkiewicz used splashing liquids to create fantastical superheroine costumes. The splashes are all real, composited together in post-production from hundreds of individual splashes. He uses cold whole milk as his base liquid, sometimes supplementing with dye or paint for color. There’s also a behind-the-scenes video showing how the pictures are made, but, fair warning, it’s in German with some English subtitles and does contain nudity (link). (Image credits: J.

“Marco Polo” Theme
Netflix’s new original series “Marco Polo” has a distinctive and fluidsy title sequence. The artistic team at the Mill created the effect by painting images in water atop dense paper before introducing Japanese sumi-ink. Using high-speed photography, they filmed the diffusion of the ink into the water as it reveals the larger picture. There’s a great behind-the-scenes break down and video over at their blog.

Light Paintings
Photographer Stephen Orlando uses programmable LEDs to create light paintings. Here floating LEDs illuminate a track down a waterfall. In flow visualization terms, this is a pathline because it records the trajectory a particular particle followed through the flow. Streamlines, streaklines, and pathlines are all important concepts for interpreting fluid flow through visualization. To see more of Orlando’s light paintings, including some wonderful portraits of canoeing and kayaking, be sure to check out his galleries. (Photo credit: S. Orlando; via Colossal)
Van Gogh and Turbulence
Turbulence is one of the great unsolved mysteries of classical mechanics. Many physicists and engineers have spent their careers trying to further our understanding of the subject and find the mathematical pattern that underlies its complex motions. But understanding turbulence and representing it artistically may be two different things. This video discusses some neat research that found that some of Vincent van Gogh’s paintings, like “The Starry Night”, display mathematical patterns like those of turbulence. (Video credit: TED Ed)
“Cymatics”
Nigel Stanford’s new “Cymatics” music video is full of stunning science-inspired visuals. The entire video is set up around various science demos–many of which will be familiar to readers–that translate sound or vibration into visual elements. The video uses ferrofluids, vibrates vodka on a speaker to create Faraday waves, and visualizes resonant sound waves with a Rubens’ tube. I don’t want to give away all the awesome effects, so watch it for yourself, and then check out their behind-the-scenes page where they talk about how they created each effect. (Video credit: N.

“Milky WaY”
Photographer Paulo Stagnaro uses milk and food coloring in his series “Milky WaY”. Despite the simple ingredients, the photos illustrate the enormous variety of shape and form in fluid dynamics. Surface tension, diffusion, and intentional mixing create abstract and ephemeral portraits of fluid motion. For similar work, see Pery Bruge’s art or just try browsing through FYFD’s “fluids as art” tag for more examples of science and art intersecting. (Photo credit: P.

“Courants et Couleurs”
Although flow visualization is a scientific technique, there is very much an art to it. Flow structures are, by their nature, ephemeral. To capture them, one must design an experiment that introduces dye into regions of interest without altering the flow significantly and without either ignoring or obscuring important physics. One of the great masters of this scientific art was Henri Werlé, whose extensive flow visualization work at France’s national aerospace lab is documented in the short film above. The film includes examples of simple geometries, full aircraft models, subsonic flow, shock waves, and more. eFluids has a whole gallery of Werlé images, too. Take a few minutes to enjoy the mesmerizing beauty of these experiments and appreciate the talents of those who made them possible. If you have questions about specific clips, feel free to ask!

“Cymatic Sun”
“Cymatic Sun” from artist Lachlan Turczan uses vibrating fluids to generate mesmerizing and surreal visuals. At some points distinct Faraday waves are visible on the surface. At other times, there is simply a blur of motion and refracted light. Check out my “fluids as art” tag for many more great examples of fluid dynamics and art merging. (Video credit and submission: L.
