Abstract

This paper presents experimental and numerical investigations onglobal forces exerted by violent irregular fluid motions during a 5-hour period (at full scale) on LNGC prismatic tanks' boundaries at a low partial filling (R=30%H). First, the experimental set-up (test rig and weighing device) is described. Second, the hydrodynamic calculation of the test case is presented. Third, the model tests with empty tank (which allow to validate the weighing device) and with the filled tank (R=30%H) are presented. Finally, the CFD (Computational Fluid Dynamics) calculations using OpenFOAM are compared to the experiments and are shown to be in very good agreement in the case of the multi-step simulation.
