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…

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…

Stress field in the vicinity of a bubble/sphere moving in a dilute surfactant solution
Hiroaki Kusuno, Yoshiyuki Tagawa
In this study, we experimentally investigate the stress field around a bubble rising in a dilute surfactant solution (20 < Re < 220, high Peclet numbers) whose surface gradually be…
