Abstract: The present study utilizes the Smoothed Particle Hydrodynamics (SPH) method for numerical simulations to systematically investigate the reduction effect of the vertical baffle quantity on the sloshing in a rectangular tank. Comparative analysis with experimental data confirms the SPH method's efficacy in simulating free surface sloshing dynamics. The study reveals that vertical baffles significantly reduce the system's natural frequency and enhance viscous damping, with an inverse relationship between baffle quantity and natural frequency, and a direct relationship with damping. Furthermore, vertical baffles are found to effectively reduce wave elevation and dynamic pressure on the free surface, with increased suppression as the number of baffles increases.
