Modeling Fluid-Structure Interaction
Abstract
We are approaching the end of our second year on this research project. We are working on the development of an integrated analytical-experimental effort to develop a physics based reduced order analytical model of the nonlinear fluid-structure interactions in articulated naval platforms. Environmental effects include forces due to waves, current, and vortex shedding. The symbiosis of analysis and experiments provides a unique opportunity to advance the state of the art in such analytical modeling by directly addressing nonlinear coupling effects, and linking individual terms in the analysis to physical parameters measured in the laboratory. This research is also an excellent vehicle for training a new generation of workers who are adept at understanding fluid-structure interaction problems both from analytical dynamics and experimental fluid dynamics perspectives. Our objectives include the following: (1) to develop a first-principles-based approach to the development of reduced order differential equations governing the coupled and nonlinear interaction between shedding vortices and structural response, and (2) to examine bending and extension in long and slender beams subject to vortex shedding, buoyancy, and wave loads. The work is coupled in that there is close collaboration between the structural and fluid mechanicians. Specifically, the reduced order analytical model that is being developed includes terms that require experimental input. Guidance and validation are proceeding in tandem.
