To mitigate vibrations, tanks partially filled with particles or liquids are often used, where the system\u2019s kinetic energy is dissipated through particle collisions or fluid viscosity. Due to the nature of the excitation and the internal geometry, the flow patterns that develop inside such tanks play a crucial role in the damping efficiency. This study aims to numerically model the flow inside a vertically excited, partially liquid-filled tank, and to build an experimental setup for validation. Following the comparison of simulation and experimental results, a reduced-order model of the tank will be developed, and the influence of different tank geometries on the flow and damping behavior will be investigated.<\/p>\n\n\n\n
