A bubble ring, or toroidal bubble, is an underwater vortex ring where an air bubble occupies the core of the vortex, forming a ring shape. The ring of air as well as the nearby water spins …

A kolk is an underwater vortex causing hydrodynamic scour by rapidly rushing water past an underwater obstacle. High-velocity gradients produce a high-shear rotating column of water, …

2025年1月16日 · In this work, we experimentally investigate the wake produced by a tethered robotic fish immersed in a water tunnel. By systematically varying the amplitude and frequency …

2024年6月2日 · More formally known as a toroidal vortex, a vortex ring is a vortex of a fluid or gas that forms around an imaginary axis line in the form of a closed loop. Basically, it looks like a …

2023年3月10日 · In this paper, we apply monocular vision in an underwater distributed swarm system, and implement vortex behavior and aggregation behavior based on it. We used two …

A small burst of air is released into a toroidal or poloidal vortex, essentially a spinning donut of water. Bubble rings are actually made of two different rings, one inside the other, spinning in …

When a small burst of air is released into a toroidal or poloidal vortex — essentially a spinning donut of water — it shapes the air into its own ring along the water’s trajectory, creating a …
