Smoothed particle hydrodynamics (SPH) is a mesh-free adaptive Lagrangian particle method with attractive features for dealing with the free surface flow. This paper applies the SPH method to simulate the large-amplitude lateral sloshing both with and without a floating body, and the vertical parametrically-excited sloshing in a two-dimensional tank. The numerical results show that the SPH approach has an obvious advantage over conventional mesh-based methods in handling nonlinear sloshing problems such as violent fluid-solid interaction, and flow separation and wave-breaking on the free fluid surface. The SPH method provides a new alternative and an effective way to solve these special strong nonlinear sloshing problems.
