Próxima semana tenemos Seminario de Sistemas Complejos en el IFIS. “Ratchet mechanism-driven motion: Towards macroscopic particle segregation” será presentado por Javier Pillado, estudiante de nuestro Doctorado en Ciencias Físicas conjunto a la USM, desde las 10:00 AM este miércoles 7 de agosto en la Sala 208 de la Facultad de Ciencias PUCV.
Te dejamos el abstract de la presentación:
Non-propagative localized driven-damped solitons are nonlinear. The dynamics of a bouncing ball on a vibrated plate is a well-studied problem that, despite its simplicity, offers a rich, dynamic behavior, including examples such as period doubling and chaos. By modifying the geometry of the plate, it is possible to introduce motion that allows for controlling the direction of propagation of a particle or segregation in the case of having many particles. This experimental investigation explores a ratchet-type mechanism and focuses on the dynamics of particles of different sizes and how they are affected by vibration parameters and ratchet geometry under vertical and horizontal oscillations, aiming to optimize the efficiency of the process in terms of both speed and quality. The experiment allows for the optimization of the granular segregation process, which can help in the development of applications for efficient filtration of waste collection on beaches.
