Séminaire Café (Interne)
Il s’agit d’un exposé assez court (20 min) et assez informel.
Prière aux conférencier·ère·s de ne jamais dépasser 30 min et de vérifier la compatibilité avec le projecteur avant le séminaire.
Les séminaires ont lieu les jeudis après la réunion du laboratoire qui débute à 13h30 dans la bibliothèque du labo sur le campus Jussieu, Barre Cassan, Bât A, 1er étage.

Coffee seminars are supposed to be short and informal presentations (20 min).
Please never last longer than 30 min and check the compatibility of the projector with your computer before the seminar.

| 28 septembre | Wilson Reino Doctorant invité Capillary surfers are wave-driven particles at a vibrating fluid interface that have been recently introduced. These active particles are characterized by high tunability and they exhibit multistability since their interaction orces are long-ranged and spatially oscillatory. Capillary surfers are asymmetric solid objects. It has been suggested that their propulsion is due to asymmetric wave generation on the liquid surface, which would result in an asymmetric transfer of momentum from the surfer to the liquid and net radiation stress. We check this propulsion mechanism by measuring the wave field of capillary surfers using a surface reconstruction technique. Wave field measurements are performed by varying forcing frequency and amplitude and with surfers with different shapes. Indeed, in all cases, the wave field asymmetry is compatible with the direction of the surfer propulsion. A comparison of the measured wave field with an existing theoretical model is also attempted. |
