Jet coronation: Coexistence of compressible and incompressible dynamics
H. Watanabe, K. Hashimoto, W. K. A. Worby +4
This paper is associated with a poster winner of a 2025 American Physical Society's Division of Fluid Dynamics (DFD) Gallery of Fluid Motion Award for work presented at the DFD Gal…
Penetration of impact-induced jets into skin-simulating materials
Kohei Yamagata, Yuto Yokoyama, Shoto Sekiguchi +3
This study compares the penetration characteristics of impact-induced jets with those of laser-induced jets, focusing on the underlying penetration mechanism rather than device per…
Interfacial dynamics induced by impacts across rigid and soft substrates
Ishin Kikuchi, Hiroya Watanabe, Yuto Yokoyama +2
We investigate impact-induced gas-liquid interfacial dynamics through experiments in which a liquid-filled container impacts substrates with elastic moduli from MPa to…
Impulse-induced liquid jets from bubbles with arbitrary contact angles
Hiroyuki Miyoshi, Hiroya Watanabe, Ishin Kikuchi +1
This paper investigates the relationship between the contact angle of a spherical bubble attached to a tube submerged in a container and the jet speed induced by an impulsive accel…
