Numerical Simulation Low Filling Ratio of Sway Sloshing in the Prismatic Tank Using Smoothed Particle Hydrodynamics

Sloshing is one of challenging problem in the free surface flow, because is dealing with large deformation of fluid. The present paper was carried out of numerical sloshing in the prismatic tank that resemble of LNG membrane type carrier. Pressure sensor was used to validate the dynamic pressure in low filling ratio of tank. Forced oscillation motion in sway with f = 1.08 Hz and amplitude of motion 6.52 mm. A single, and double vertical baffles are used to reduce dynamic pressure and hydrodynamic force. The ratio of baffle heigh with water depth is 0.9. A meshless computational fluid dynamics (CFD) was used to reproduce sloshing in the prismatic tank. Smoothed particle hydrodynamics (SPH) is one of the major meshless CFD. In addition, The advanced visualization was performed using Blender version 2.92. The results showed the vertical baffles effectively reduce the dynamic pressure and hydrodynamic force. Moreover, the advanced visualisation made sloshing simulation more realistic, and attracting compare conventional SPH post-processing.
