Abstract


In the present contribution a pendulum-based model is used to represent fluid-structure interactions. For this purpose, a theoretical and experimental
analysis of the dynamic behavior of a viscously damped spherical non rotational single-degree-of-freedom pendulum was performed. The damping
process is characterized according to two different regimes: in the first, it can be seen as a viscous low Reynolds’ number flow and, in the second, it can be considered as a viscously damped system. The pendulum was tested experimentally in a large reservoir containing a Newtonian fluid for validation purposes and good agreement was found between numerical and experimental results.
