Description/Abstract

Sloshing phenomenon consists in the movement of liquids inside partially filled tanks, which
generates dynamic loads on the tank structure. Resulting impact pressures are of great importance in assessing
structural strength, and their correct evaluation still represents a challenge for the designer due to the high
nonlinearities involved, with complex free surface deformations, violent impact phenomena and influence of air
trapping. In the present paper a set of two-dimensional cases for which experimental results are available are
considered to assess merits and shortcomings of different numerical methods for sloshing evaluation, namely two
commercial RANS solvers (FLOW-3D and LS-DYNA), and two own developed methods (Smoothed Particle
Hydrodynamics and RANS). Impact pressures at different critical locations and global moment induced by water
motion for a partially filled tank with rectangular section having a rolling motion have been evaluated and results
are compared with experiments.
