03 Ring fountain
When a flat metal ring falls from a certain height into a water tank, it generates a fountain that can shoot water high into the air. How does the maximum height of the fountain depend on the ring's parameters?

  • Giant Bubble Pinch-Off

    The paper investigates how a disk pulled rapidly through the water surface creates a large air-filled cavity (‘giant bubble’), which collapses in a pinch-off that drives a vertical jet. The authors analyze the cavity dynamics and visualize the process with high-speed imaging.

  • High-speed Jet Formation after Solid Object Impact

    The paper investigates how the collapse of an air cavity, formed when a disk impacts a liquid surface, produces upward and downward high-speed jets. The authors show through simulations that the jets are powered by fluid flow from the collapsing cavity walls, and they develop a simplified theoretical model that quantitatively captures the jetting process.
