Roughening dynamics of spontaneous radial imbibition
Yong-Jun Chen, Kenichi Yoshikawa
We performed an experimental observation on the spontaneous imbibition of water in a porous media in a radial Hele-Shaw cell and confirmed Washburn's law, where r is distance and t…
Anomalous roughening of forced radial imbibition in a porous medium
Yong-Jun Chen, Shun Watanabe, Kenichi Yoshikawa
We report forced radial imbibition of water in a porous medium in a Hele-Shaw cell. Washburn's law is confirmed in our experiment. Radial imbibition follows scaling dynamics and sh…
Dynamic Labyrinthine Pattern in an Active Liquid Film
Yong-Jun Chen, Yuko Nagamine, Kenichi Yoshikawa
We report the generation of a dynamic labyrinthine pattern in an active alcohol film. A dynamic labyrinthine pattern is formed along the contact line of air/pentanol/aqueous three…
Self-Propelled Motion of a Droplet Induced by Marangoni-driven Spreading
Yong-Jun Chen, Yuko Nagamine, Kenichi Yoshikawa
We report the generation of directed self-propelled motion of a droplet of aniline oil with a velocity on the order of centimeters per second on an aqueous phase. It is found that,…
