Nonlinear sloshing analysis in a three-dimensional rectangular pool

Uzawa, Ken

To prevent anomalous events of equipment and structures in a spent fuel pool from occurring, it is essential to comprehend overflow of water and fluid pressure caused by sloshing. For this purpose, it is necessary to quantitatively evaluate turbulent dissipation near water surface and inner structures instead of an empirical value which depends on size of each pool. In this research, we test the efficacy of turbulence models by performing numerical simulation of dam break phenomenon and sloshing in a rectangular pool to evaluate turbulent dissipation based on action mechanism. As a result, we demonstrated that numerical heights by Reynolds stress model and Large Eddy Simulation are in well agreement with experimental value.
