Abstract:
Swimmers in nature use body undulations to generate propulsive and manoeuvring forces. The body shape of the swimmer and its motion kinematics act in concert to determine these forces and the associated energy expenditure. I will present our recent work on the fluid-structure interaction problem that underlies these questions, using a flexible thin plate as a minimal model of bio-inspired undulatory swimmer. In a second part of the talk I will discuss the problem of collective dynamics that we have explored using experiments with real fish.
Bio:
Dr. Godoy-Diana is a CNRS research scientist at the Physique et Mécanique des Milieux Hétérogènes laboratory (PMMH) at ESPCI in Paris, France. Physical engineer from the Tec de Monterrey (México, 1994), he holds a Master in Physics from the UNAM (México, 1999) and a PhD in fluid dynamics from École Polytechnique (France, 2004). His experimental fluid dynamics work has included research on ocean wave energy, geophysical fluid dynamics, wake instabilities, fluid-structure interaction and bio-inspired propulsion. He co-heads the Biomimetics and fluid-structure interaction group at PMMH.
