Abstract

Sloshing tests are performed on a rectangular tank filled with bottom-mounted vertical cylinders, around the natural frequency of the first sloshing mode. The numbers and heights of the cylinders are varied. From the position of the resonance peak an experimental dispersion equation is derived, and compared with different formulations from literature. A new formulation is proposed. A modal approach is then applied to derive the RAO of the sloshing response, and compared with the experimental results.

Short bio

Professor Bernard Molin has for the last years been a professor at École Centrale de Marseille. His research activities have been mainly concerned with nonlinear hydrodynamics (drift forces, slow drift motion, high frequency loads and response), and development of computer models for the French offshore industry. Recent involvement has included hydrodynamics of perforated structures, Vortex Induced Vibrations, slamming, moon-pool resonances, hydroelastic responses, sloshing in tanks and motion coupling, run-up effects and slow-drift excitation.
