“…Wang et al [28] analyzed the influence of porous baffles on sloshing under a rotational excitation using numerical simulation, finding that increasing the height of the baffle while decreasing the porosity of the baffle could both enhance the wave-damping. Nimisha et al [29,30] explored the effect of different porosities on swaying; they concluded that the optimum perforation was within the range of 10~17%. In this range, the porous baffle effectively suppressed the intensity of liquid sloshing on resonance.…”

Liquid sloshing is a common phenomenon in ocean engineering, and one which not only affects the stability of ship navigation, but also poses a threat to both the marine environment and human life. Ascertaining how best to reduce the amplitude of liquid sloshing has always been a key problem in ocean engineering. In this study, based on an improved moving-particle semi-implicit method, the BM-MPS method, the damping effect of a vertical slotted screen under rotation excitation was simulated and studied, and the influence of baffle porosity and the rotation amplitude on the resonance period and impact pressure was discussed. The results showed that the porosity had an obvious effect on the resonance period. A significant resonance period transformation happened when the porosity was 0.1, but a porosity of 0.15 was the point at which the maximum impact pressure in the resonance was at its minimum. Meanwhile, the impact duration curve was related to porosity. With the increasing of porosity, the impact duration curve changed from having no peak to a single peak, and then to double peak. In addition, the amplitude of rotation excitation was also one of the factors that affected the resonance period.
