摘要：
The sloshing free vibrations and the Equivalent Mechanical Model (EMM) parameters are determined for 2D multi-baffled containers under low-gravity conditions using Boundary Element Method (BEM) and potential flow model of the fluid. The presented model is applicable to any values of the acceleration of gravity and surface tension and to constant cross-section containers with arbitrary geometry, and baffle arrangement and shape. The results for a simple rectangular container are validated compared to the analytical values and very good agreement is achieved. Some baffled containers are also analyzed and their sloshing natural frequencies and EMM parameters are presented under low and zero-gravity conditions. Moreover, the effect of baffle characteristics on these parameters is investigated in a wide range of the acceleration of gravity and some conclusions are outlined.
