Inclination-Induced Crossover in the Velocity Scaling of Lubrication-Mediated Droplet Motion
Haruka Hitomi, Ko Okumura
We experimentally investigate the creeping motion of water droplets sliding along an inclined surface immersed in a viscous oil. The droplet velocity, width, and height are measure…

Continuous generation of confined bubbles: viscous effect on the gravito-capillary pinch off
Haruka Hitomi, Ko Okumura
We investigate continuous generation of bubbles from a bath of air in viscous liquid in a confined geometry. In our original setup, bubbles are spontaneously generated by virtue of…
