SATURDAY MORNING PHYSICS
How Flexible Bodies Move and Interact in Fluids
Swimming fish use a wide range of body and fin motions to propel themselves through fluids. Professor Alben and collaborators study the motions of a generic type of fish body--a flexible sheet--in a fluid. They use computer simulations and laboratory experiments to understand the basic physics of these fluid-structure interactions. Professor Alben will discuss the attraction of flexible bodies to vortices, and how multiple flexible bodies can interact through their vortex wakes.
