👉 The hamburg fluid, also known as the hamburg vortex, is a fascinating fluid dynamic phenomenon that arises when a thin, viscous liquid is subjected to a rotating shear flow, typically in a cylindrical channel. This setup causes the fluid to develop a characteristic spiral structure and a central core where the velocity is zero, surrounded by a region of counter-rotating vortices. The fluid's behavior is characterized by the formation of a "hamburger-like" vortex core, which exhibits complex interactions with the surrounding fluid layers. This intricate pattern is driven by the balance between viscous forces and centrifugal forces, leading to a stable yet dynamic flow structure that has been extensively studied for its applications in understanding turbulence and mixing processes.
