Each year, the American Physical Society’s Division of Fluid Dynamics holds an annual meeting where they showcase the mesmerizing beauty of flowing fluids. This event includes a contest that recognizes outstanding images and videos related to the dynamics of liquids and gases. The 76th meeting, held in Washington, D.C. in November, unveiled a collection of captivating artistic creations. Let’s dive into the winners and explore the fascinating world of fluid dynamics.
One of the winning entries in this year’s contest shed light on the intricacies of 3D polymer printing. The team from Princeton University documented the effects of inadequate printing rates and amounts of polymer material. The resulting pattern showcased a delicate lace-like structure with controlled gaps, demonstrating a more efficient printing process. By adjusting the layer height and rate of printing, they managed to manipulate the density of the final printed structure. Watching the accompanying video, set to Bach’s Violin Sonata No. 2 in A Minor, invites viewers to appreciate the beauty created within the realm of emerging technology.
Another captivating entry in the contest was a numerical simulation image titled “Drop Medusa.” By inducing vibrations in a small liquid drop in zero gravity, researchers observed the formation of mesmerizing patterns resembling the husk of a chestnut tree. These patterns, reminiscent of the mythical Medusa’s hair, were the result of high-amplitude radial vibrations at a frequency of 1040 Hertz. The chaotic waves created by the wave superpositions formed the jet and crater effect as the drop disintegrated. This fascinating study delves into the interplay between hydrodynamics and elasticity, potentially offering insights into various scientific fields, from biology to engineering.
Revealing the Frost’s Journey
An enthralling video showcased the intricate dynamics of frost propagation. When moisture comes into contact with a cold surface, breath figures, or water droplets, form. In the video, a sudden cooling of the surface triggers the freezing of the droplets, releasing latent heat. The process of frost formation commences as the droplets freeze from the surface up, creating delicate ice bridges between them. The mesmerizing movements and transformation captured in the video highlight the graceful dance of nature’s freezing touch.
The “Traveling Gallery of Fluid Motion”
Beyond the winners, there are numerous other captivating entries that deserve admiration. The “Traveling Gallery of Fluid Motion” exhibition, presented by the American Physical Society’s Division of Fluid Dynamics, offers an immersive experience into the artistry of fluid flow. Currently hosted at the Cultural Program of the National Academy of Sciences (CPNAS) in Washington, D.C., the exhibition, titled “Chaosmosis: Assigning Rhythm to the Turbulent,” invites visitors to delve into the mesmerizing world of fluid dynamics. From October 2023 to February 2024, attendees can explore the exhibition’s various displays, showcasing the captivating beauty intrinsic to the interplay of liquids and gases.
The Endless Fascination of Fluid Dynamics
Fluid dynamics continues to mesmerize both scientists and artists with its inherent beauty and complexity. The annual meeting of the American Physical Society’s Division of Fluid Dynamics provides a platform for sharing and appreciating the stunning visuals that emerge from the world of fluid flow. As we delve into these intricate and captivating images and videos, we gain a deeper understanding of the hidden complexities underlying the natural phenomena that surround us. Whether it is the delicate lace-like structures formed by 3D polymer printers or the chaotic patterns resulting from vibrating liquid drops, these entrancing creations remind us of the boundless wonders and artistry found within the realm of fluid dynamics.
