1. Fluid-structure interaction

Phenomena linked to fluid-structure mechanical coupling occur, to varying degrees of importance, in any structure in contact with a fluid. This type of multi-physics coupling is encountered in many industrial situations, and the influence it can have on the dynamic behavior of mechanical systems is often significant.

Taking into account the effects of fluid-structure coupling is therefore becoming a key factor in the design of structures, particularly in view of the safety requirements associated with their design. The ongoing development of numerical calculation techniques, and the ever-increasing computing capacity of machines, make it possible to implement complex numerical simulations, involving various couplings.

The mechanical coupling between the two media takes place in both directions at their contact surface: the vibrations of...
