Fluid dynamics is a captivating branch of physics that studies the behavior and motion of fluids, such as liquids and gases. Each year, the American Physical Society’s Division of Fluid Dynamics organizes a contest to celebrate the mesmerizing beauty and scientific significance of fluid flow through captivating images and videos. In this article, we will delve into some of the remarkable winners of the 76th meeting of the Division, held in Washington, D.C., showcasing the diverse and awe-inspiring aspects of fluid dynamics.
The Art of 3D Polymer Printing
At Princeton University, a team of researchers explored the delicate art of spooling materials in 3D polymer printers. They discovered that when insufficient material is deposited too slowly, a fascinating pattern emerges. The resultant structure resembles intricate lace with intentional gaps, rendering it stable and efficient. By manipulating the layer height and printing speed, the researchers were able to control the density and appearance of the final printed structure. The mesmerizing video accompanying this research is accompanied by the enchanting tones of Bach’s Violin Sonata No. 2 in A Minor.
In a mesmerizing display of fluid dynamics, researchers induced vibrations in a small liquid drop, creating an intricate pattern of “jets” and “craters.” The image, aptly named the “Drop Medusa,” bears a striking resemblance to the husk of a chestnut tree seed. This phenomenon occurs when radial vibrations with high amplitude interact with the drop, leading to chaotic nonlinear waves that ultimately cause the drop to burst apart. This research sheds light on the intriguing interplay between hydrodynamics and elasticity, potentially impacting diverse fields such as biology, naval engineering, and aerospace structures.
The formation of water droplets on a cold surface, known as “breath figures,” has long fascinated scientists. When the surface abruptly cools, the droplets freeze and release latent heat. Through the lens of an infrared camera, researchers captured the freeze-propagation process, capturing the mesmerizing transformation as frost forms and creates ice bridges between individual droplets. This exhibition of winter’s beauty showcases the intricate movements and features within the frozen droplets, adding another layer of enchantment to the realm of fluid dynamics.
The captivating world of fluid dynamics is brought to life through the “Traveling Gallery of Fluid Motion” exhibition, presented by the American Physical Society’s Division of Fluid Dynamics. The exhibition, aptly titled “Chaosmosis: Assigning Rhythm to the Turbulent,” takes viewers on a visual journey that explores the mesmerizing interplay of fluid flow. From October 2, 2023, to February 23, 2024, visitors can experience this breathtaking exhibition at the Cultural Program of the National Academy of Sciences in Washington, D.C. Located at 2101 Constitution Ave., N.W., the exhibition invites viewers to immerse themselves in the captivating world of fluid dynamics.
Fluid dynamics, with its magnificent patterns and mesmerizing behaviors, continues to captivate scientists and enthusiasts alike. Through the lenses of researchers and the American Physical Society’s Division of Fluid Dynamics, we gain a deeper understanding of the intricate interplay between fluids and their surroundings. From the delicate art of 3D polymer printing to the enigmatic “Drop Medusa” and the captivating frost propagation, each aspect showcases the elegance and complexity of fluid flow. As we explore the Traveling Gallery of Fluid Motion, we are invited to embark on a visual journey that celebrates the captivating beauty and scientific significance of fluid dynamics.
