In this study, Smoothed Particle Hydrodynamics (SPH) method was used to model sloshing response of
a rectangular tank subjected to horizontal earthquake base excitation. An experiment and a numerical
study with ANSYS Fluent flow modeling software are performed to verify the outputs of the SPH model.
The sloshing displacement profiles obtained from the SPH model closely matched the free surface
displacements obtained from the experiment and the flow modeling software. The SPH model
described in this study was highly efficient at capturing discontinuities and working with moving
boundaries without having to re-mesh the model at each time step.
