摘要：

Various variational formulations for the linear vibrations of bounded fluid-structure systems, taking into account possible gravity/acoustic interactions are investigated and discussed. The system consists of a tank partially filled with an inviscid liquid. Two situations corresponding to the cases of a homogeneous and a non-homogeneous liquid are considered. In this respect, the basic equations describing the interactions between acoustic and gravity waves are derived and appropriate variational formulations are constructed. (c) 2005 Elsevier B.V.
