Numerical Simulation of Sloshing in Roll Motion on Multiple Tanks with Vertical and Horizontal Baffle Using Smoothed Particle Hydrodynamics

Computational Fluid Dynamics (CFD) is a numerical analysis used in solving problems related to water flow. Many methods have been created in the application of CFD, one of which is Smoothed Particle Hydrodynamics (SPH). SPH is a meshless method where each fluid is represented by a particle. In this study, a 3D simulation was carried out for the phenomenon of sloshing with roll motion in prismatic, square, cylindrical and spherical tanks with a duration of 28 seconds. The filling ratio was carried out at 25% with the addition of vertical baffles and horizontal baffles at each water filling ratio. The results of this study show a comparison of dynamic pressure, freesurface heights, dorces and moments in various tank variations. The addition of baffles to the tank in this study has an influence on the sloshing phenomenon, especially in the use of vertical baffles. where the vertical baffle is the most effective baffle used in all tanks.
