Flexing, Fluttering, and Singing: Fluid-Structure Interactions in the Marine Environment presented by Assistant Professor Casey Harwood, Mechanincal & industrial Engineering, University of Iowa. Abstract: Fluid-structure interactions (FSI) is a field at the crossroads of fluid dynamics and structural dynamics that studies the response of flexible bodies to fluid loads and the simultaneous modifications of those fluid loads by structural motions. In extreme cases, the coupling between the fluid loads and structural motions can result in noise, vibration, and even destructive instabilities. Hydroelasticity is a variety of FSI occurring in the marine environment.  Examples include the beam-like flexure of ship hulls, the vibration of ship structures following wave impacts, and the deflection of propeller blades subjected to large propulsive loads. In this talk, I will offer a brief survey of the field of hydroelasticity and its relevance to modern shipping and defense. I will also discuss recent experimental campaigns at the University of Michigan and the Italian National Research Council (CNR-INSEAN). The experiments used novel instrumentation and experimental techniques to study the steady and unsteady interactions between two- and three-component flows and a flexible hydrofoil. Key results and areas for future development in experimentation, computation, and reduced order modeling will be identified.
