Fluid dynamics, a branch of physics that studies the motion and behavior of fluids, has long been considered as a complex and technical field. However, at the American Physical Society’s annual meeting, the Division of Fluid Dynamics reveals an extraordinary side of this discipline through their captivating images and videos. In this article, we will delve into the mesmerizing world of fluid dynamics and explore the winners of the contest, showcasing the stunning beauty hidden within the flow of fluids.
Princeton University’s team showcases the delicate intricacies of 3D polymer printers in their video entry. The mesmerizing pattern unfolds as too little material is printed too slowly, resulting in orderly and stable layers resembling lace, albeit with gaps in its structure. This phenomenon demonstrates how the density of the final printed structure can be controlled by adjusting the height of each layer and the printing rate.
A group of researchers captures a striking pattern resembling a chestnut tree’s husk, aptly named “Drop Medusa.” By inducing high-amplitude radial vibrations at a frequency of 1040 Hertz, chaos engulfs a small liquid drop in zero gravity, creating nonlinear waves that form “jets” and “craters.” The interplay between hydrodynamics and elasticity generates this captivating display, shedding light on the complex fluid dynamics at play.
The interaction between objects dropped onto a liquid water surface and the resulting hydroelastic effects fascinates scientists in the field of fluid dynamics. The impact’s force creates vibrations that give rise to peculiar undulations along the walls of the air cavity formed around the object upon entry. Understanding this interplay could have significant implications for diverse fields, including biology and engineering.
Water droplets on a cold surface create intricate patterns as they freeze and release latent heat. Infrared cameras capture the enchanting process of droplets freezing from the surface up, with frost propagating by forming ice bridges between individual droplets. The final result is a stunning display of frozen droplets crowned by a delicate icy point, showcasing the beauty that arises from the interaction between fluid and cold surfaces.
These awe-inspiring images and videos represent just a glimpse into the world of fluid dynamics showcased at the American Physical Society’s Division of Fluid Dynamics’ annual meeting. The “Traveling Gallery of Fluid Motion” exhibition, titled “Chaosmosis: Assigning Rhythm to the Turbulent,” promises to captivate visitors with its exploration of the connection between art and science. From October 2, 2023, to February 23, 2024, the Cultural Program of the National Academy of Sciences will host this mesmerizing exhibition at 2101 Constitution Ave., N.W., Washington, D.C. Prepare to be amazed by the captivating beauty that unfolds within the flow of fluids.
The artistry of fluid dynamics proves that even in the most technical and scientific fields, beauty can be found. The winners of the American Physical Society Division of Fluid Dynamics’ contest reveal the intricate patterns, mesmerizing movements, and enthralling phenomena that exist within the flow of fluids. From 3D polymer printing to the dance of frost, each entry showcases the stunning beauty of fluid dynamics and sheds light on the captivating interplay between hydrodynamics, elasticity, and the complexities of the natural world. As we delve into the captivating images and videos presented by this year’s winners, we gain a newfound appreciation for the elegance and intricacy that the world of fluid dynamics holds.
