Workshop at Les Houches

The study of the mechanisms underlying animal swimming and flying has long motivated research efforts in the physical and biological sciences. Beyond the simple goal of understanding the fundamental question of animal locomotion, these problems have also inspired developments in engineering. It has certainly become commonplace to mention Leonardo da Vinci’s sketches of flying machines in most lectures and courses dealing with bio-inspired mechanics. The last quarter century has seen a huge increase in work on these topics at the interface of physics and biology, driven in part by the democratization of experimental fluid mechanics tools in biology labs (notably particle image velocimetry and high-speed video).

The objective of this workshop was to provide a collective picture of the state of the art and to indicate the avenues of research that we envision for the future. We focused on the macroscopic side of the broad topic of biolocomotion in fluids. We addressed animal locomotion problems such as fish swimming or flapping flight, where fluid-structure interactions between a deformable body and its environment are placed in the context of vortex-dominated flows. In addition to the problem of pure locomotion, questions of interactions between individuals and collective behavior were widely considered. Beyond the (bio)mechanics of the bodies involved, their actuation and passive elastic responses, and the fluid forces of the environment, we also devoted part of the discussion to sensory feedback systems, which are an intrinsic part of these unsteady problems.

Looking forward to other meetings with this great crowd!

UPtoPARIS

ESPCI proposes a brand new international doctoral programme – UPtoPARIS: More info here: https://www.upto.paris/-upTo-paris-.html

The first call closes on February 28th, 2018. Our project on bio-inspired wave-energy conversion is one of the projects selected (project page here).

Bio-inspired elastic structures for ocean wave energy conversion

The purpose of this project is to study a surface wave absorbing system with potential for both coastal erosion control and renewable energy production. The system is inspired by the fluid flow calming effects of aquatic vegetation in near-shore and riverine environments. The system consists of an ensemble of flexible slender structures mimicking an underwater canopy whose collective dynamics is forced by the action of the waves. The reconfiguration of slender structures by their interaction with an external flow has been a vibrant subject of research in the past decade, and applications abound in this archetype of interdisciplinary subject where biology, physics and engineering meet.
