IUTAM Symposium On Integrated
Modeling of Fully Coupled Fluid-Structure Interactions Using Analysis,
Computations, and Experiments 1 June-6
June 2003
Department of Mechanical and Aerospace Engineering Location and Directions to Zimmerli Art Museum, Rutgers University This Symposium
will provide a forum for the latest thinking in analytical, computational and
experimental modeling of structures interacting with fluid environments. The specific objective is to provide a
structured format in which meaningful and lasting dialogues can be
facilitated between leading researchers in the different component
disciplines. It is intended that, through
these dialogues, multidisciplinary linkages will be established leading to
integrated approaches to modeling 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 behavior.
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 behavior. 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 modeling 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 can only come from fully coupled models. That is, the structure and the fluid need
to be modeled at a comparable level of accuracy. The real
fluid-structure system is one of complex exchanges of forces and energies,
resulting in highly nonlinear behaviors.
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. By
bringing together a critical mass of key researchers in each discipline, and
organizing the program to focus on multidisciplinary problem solving, this
process of developing fully coupled fluid-structure interaction research
programs can be reinforced and enhanced.
We look forward to receiving abstracts for review, presentation, and
eventual full publication, of topics that fall within the broad framework
defined above. Abstracts may be submitted to Prof. Haym Benaroya or Prof. Timothy Wei either in WORD or PDF as an attachment, or in text format in the body of an email. If as an attachment, please put it in US letter format. An extended abstract, roughly 1-2 pages with a figure or two would be appropriate. There should be enough information so that the organizers can make a proper assessment. Email : Prof. Haym Benaroya ( benaroya@rci.rutgers.edu )
