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…

Effect of converging shape of container on the velocity of impact-induced focused liquid jet
Hiroya Watanabe, Hiroaki Kusuno, Yoshiyuki Tagawa
We investigated the effect of container shape on the behavior of the impact-induced focused liquid jets by dropping a converging-shaped container (e.g., Kjeldahl flask) partially f…
