Abstract

Abstract: Hydrodynamics of an anti-sloshing technique using floating foams in a rectangular liquid tank is investigated. A series of experiments are conducted. An analytical potential-flow solution is derived to help explain the experimental observations. Effects of various layers of floating foams on both the wave profiles and dynamic pressure histories in sloshing tanks are analyzed. It shows that even a single layer of floating foams can help reduce the sloshing amplitude due to energy dissipation. If multiple layers of floating foams are further applied, the sloshing amplitude can be further reduced. The amplitude of dynamic pressure in the tank is also found to decrease as the number of foam layers increases. Besides, anti-sloshing effects of floating foams in tanks of different depths are discussed. Floating foams are found to work more efficiently for larger amplitude sloshing waves. Highlights: An anti-sloshing technique based on floating foams is introduced. Hydrodynamics of sloshing tanks with floating foams is investigated. Both analytical and experimental investigations are carried out. Effects of floating foams on wave elevation and sloshing pressure are discussed.
