Abstract
Liquid sloshing in partially filled tanks can cause the structural damage and system instability in multiple fields, especially for the ocean transportation system. To improve the efficiency of anti-sloshing and wave-damping in the tank, the porous structures can be adopted. In this study, the porous media theory is applied to simulate the porous baffles for analyzing the influence of the porous baffles on the sloshing flow due to a roll motion. The numerical model of porous baffles is firstly validated by comparing with the dam-breaking and sloshing experiment, and then the effects of the baffle arrangement and excitation frequencies on the wave damping performance are analyzed in detail. It was found that the porous baffle has a poor wave-damping performance when the excitation frequency is close to the first-order natural frequency. The wave damping performance can be enhanced by increasing the height of the baffle and decreasing the porosity coefficient of the baffle, and moving the porous baffle to the water surface.
