Hydrodynomechanics: Fluid-Structure Interaction
The term hydrodynomechanics refers to any phenomenon involving the dynamic response of a solid and the mass and momentum transfer in a fluid. In this chapter, hydrodynomechanics will be introduced as three distinct areas: dynamic poroelasticity, acoustic-structure interaction, and complete fluid-structure interaction. The theory of dynamic poroelasticity has been given in poroelasticity, so this chapter only includes a short section to offer more details regarding its implementation and application. For the complete fluid-structure interaction, we will show the idea of region coupling and give detailed procedures for implementing such coupling. Next, the acoustic-structure interaction will be introduced in a similar way. The differences and connections between the complete fluid-structure interaction and acoustic-structure interaction problems will be pointed out both in theory and in their applications. A simple example to show the implementation of the complete fluid-structure interaction will be presented in the final.
