Summary

This Symposium, and these Proceedings, provided a forum for the latest thinking in analytical, computational and experimental modelling of structures interacting with fluid environments. A meaningful and lasting dialogue was facilitated between leading researchers in the different component disciplines. It is intended that, through these dialogues, multidisciplinary linkages will be establishes leading to integrated approaches to modelling the complex, nonlinear interactions between fluids and structures. Examples of classes of interactions that may be addressed in this Symposium include ocean structures, fluid conveying structures, and aerospace structures. The energy transfer processes are inherently nonlinear in all aspects of the behaviour. The important class of vortex-induced oscillations has regions of lock-in, where the structural natural frequencies rather than the fluid velocity govern the shedding, and there exists hysteretic behaviour. A large body of engineering and engineering science is concerned about fluid-structure interactions. Yet there are many unanswered questions about the underlying physics, so much so that a great deal of empiricism remains. Much of this empiricism can be traced to the relative lack of detailed collaboration between the fluid and structural mechanics communities studying these interactions. Generally, it has been that structural mechanicians would place extensive effort into the structural model, while a simple oscillator represented fluid motions. Conversely, fluid mechanicians placed most of their modelling efforts into the fluid, often considering the structure to be a rigid single degree of freedom oscillator. While such studies have significantly increased understanding, it appears that the next breakthroughs in the field need to be modelled at a comparable lever of accuracy.The real fluid-structure system is one of complex exchanges of forces and energies, resulting in highly nonlinear behaviours. The ability to model, solve and test fully coupled fluid-structure systems portends a rich and profound understanding. In fact, recent research efforts have indeed started to focus on the development of fully coupled models. This Symposium is therefore a response to these new and exciting developments in the field.
