Numerical Simulation of Long Duration Sloshing Using Smoothed Particle Hydrodynamics

Abstract The sloshing phenomenon is one of the events in a liquid carrier vehicle such as airplanes and ships. Sloshing is a dangerous phenomenon because sloshing can effect ship motions that create excessive motion in liquid carrier vehicles. Long duration sloshing is challenging problems to solve using smoothed particle hydrodynamics (SPH). Stable, accurate, and reliable computation time is tried to achieve by many researchers. In this study, long-duration sloshing in the prismatic tank is tried to reproduce using single-phase and two-phase SPH. Firstly, the experiment is carried out using prismatic tank, with three pressure sensors, and a forced oscillation machine. In this study, only roll motion is used to reproduce hydrodynamics pressure with a low filling ratio. The results show SPH could reproduce fairly hydrodynamics pressure with spurious pressure oscillation. Static pressure is well reproduced by SPH.
