1. Fluid-structure interaction

1.1 Examples of IFS in hydrodynamics

In hydrodynamics, the effects of fluid-structure interaction can manifest themselves in a variety of situations, and need to be accounted for using appropriate modeling, as well as accurate and efficient numerical methods to represent them in a numerical simulation.

A calculation is usually carried out to answer a design question, as discussed later in this article. Simulation is then used to :

• justify the qualities and performance expected of a concept. This involves calculating a given physical quantity (air or water speed for a flow around a wing, blade or hull; the value of the mechanical forces exerted on an object; the deformation it undergoes in return; the intensity...
