Non-stationary dynamics and coupled oscillations

Abstract

Inspired by a presentation of Sanjay Mittal [245, 250, 260] and a discussion with Paolo Galdi (private communication, 2016) we study the interaction of the von Kármán vortex sheet with the oscillation of an elastic obstacle. The flow around a blunt body develops self-excited oscillations. Elastic structures freely oscillate with Eigenfrequencies. We want to study the interplay between these two effects on a coupled elastic fluid-structure interaction problem.
