The present mini-symposium deals with flexible structures strongly coupled to heavy fluids, such as water, oil or liquid metals. These interactions are characterized by significant inertial and damping effects associated to the fluid, as well as potential multi-components (liquid-gas) and/or multi-phase (liquid-vapor) flows with interfaces yielding specific loadings on the structure. Numerous physical situations are addressed by this topic, such as dynamics of fuel rods or fuel assemblies inside a nuclear core, sloshing in tanks under seismic loading or in flight conditions, wave impact on off-shore structures… The mini-symposium thus proposes to bring together models and numerical methods dedicated to such physics, for the contributors and the audience to identify the convergences which could be exploited for mutual progress. It does not exclude the presentation of some specific issues, which shall contribute to the general understanding of the behavior of this kind of coupled systems.
Practically, many types of contributions are welcome as long as structures (of any kind) and the fluids introduced above are involved, from the exposition of dedicated numerical methods (for instance, for structural failure under fluid loading, for fluid interface tracking in interaction with moving structures or for the analysis of complex systems through porous models…) to the detailed analysis of one physical topic. The scientific content is however expected to be clearly related to a significant industrial issue and the proposed case studies should show the relevant level of complexity to provide useful methodological knowledge for researchers and engineers dealing with these issues. Advanced and innovative experimental analyses, dedicated to the supply of validation data for fluid-structure models and methods or to the reproduction, at small or actual scale, of a specific system for the understanding of its coupled dynamics, would also be of great interest.
