Abstract
Liquid sloshing phenomenon is encountered whenever a liquid in a container has an unrestrained surface and can be excited. Specific type of sloshing motion can occur during the core meltdown of a liquid metal reactor. This phenomenon was studied in series of centralized sloshing experiments with a central water column collapsing inside the surrounding cylindrical tank. These experiments provide data for a benchmark exercise for accident analysis codes. To simulate centralized sloshing phenomenon a numerical method should be capable to predict motion of free surface of liquid, wave propagation and reflection from the walls. In series of numerical calculations it is shown that overall motion of the liquid is in a good agreement with experimental observations. Dependence on the initial and geometrical symmetry is studied and compared with experimental data.
