ABSTRACT
Many physical effects can be observed when a solid body vibrates in the presence of a fluid. These are explained by the presence of a coupling between the movement of the structure and that of the fluid. We can highlight these using some simple experiments (it is enough to agitate our hand in water to feel the effects of one or the other). It is said that there is interaction between the fluid and the structure. There are numerous applications where this phenomenon of interaction between a fluid and a moving solid (rigid or deformable) occurs in aerodynamics, hydrodynamics, biomechanics, nuclear security, and in environmental protection.
