Study on the Damping Effect and Mechanism of Vertical Slotted Screens Based on the BM-MPS Method

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