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…
Optimal standoff distance for a highly focused microjet penetrating a soft material
Daichi Igarashi, Kento Kimura, Nanami Endo +3
A needle-free injector using a highly focused microjet has the potential to minimize the invasiveness of drug delivery. In this study, the jet penetration depth in a soft material-…
The effects of cavitation position on the velocity of a laser-induced microjet extracted using explainable artificial intelligence
Daichi Igarashi, Jingzu Yee, Yuto Yokoyama +2
The control of the velocity of a high-speed laser-induced microjet is crucial in applications such as needle-free injection. Previous studies have indicated that the jet velocity i…
A phase diagram of the pinch-off behavior of impulsively-induced viscoelastic liquid jets
Asuka Hosokawa, Kyota Kamamoto, Hiroya Watanabe +3
In this study, we systematically investigate the behaviors of viscoelastic liquid jets using an impulsive force, particularly in the high velocity and high elasticity regimes. The…
