Description
We are interested in the modeling and the numerical approximation of constrained flows. Previously, a shallow water type model with a congestion constraint and its numerical resolution was proposed [1].
In order to simulate floating structures such as marine energy devices, the fluid-structure interaction of an object freely floating at the water surface is considered.
The coupling with Newton's second law of motion and angular momentum theorem is explained and attention is paid to the energy of the system.
The numerical approach introduced in [1] is adapted to take into account a strong coupling with the dynamics of a floating object. Furthermore the dissipation of mechanical energy is ensured. Numerical results are shown in a one dimensional framework.
