چکیده    The present study is to carry out a numerical sloshing using smoothed particle hydrodynamics (sph) in the prismatic tank. sloshing is a violent flow caused by the resonance of fluid in the tank by external oscillation. the prismatic tank was used to resemble a membrane lng type carrier. the sloshing experiment was carried out using three pressure sensors, a camera high resolution, and four degrees of freedom forced oscillation machine. in this study, a filling ratio of 25% was used to reproduce sloshing in a low filling ratio. only roll motion is used in the numerical simulation. roll motion is directly imposing from the experiment displacement, and a comparison of hydrostatic and dynamic pressure was made to validate the sph result. the time duration of the sloshing is the same as the experiment. single-phase and multiphase sph are conducted to reproduce sloshing in the prismatic tank. sloshing was done both for the 2d and 3d domain. it shows that sph has a good agreement with analytical and experimental results. the dynamic pressure is similar to an experiment through a spurious pressure oscillation exist. the dynamics pressure results show fairly for short time simulation and slightly decrease after that. the free surface deformation tendency is similar to experiment.
