Using linear water wave theory, three-dimensional problems concerning the interaction of waves with spherical structures in a fluid which contains a three-layer fluid consisting of a layer of finite depth bounded above by freshwater of finite depth with free surface and below by an infinite layer of water of greater density are considered. In such a situation timeharmonic waves with a given frequency can propagate with three wavenumbers. The sphere is submerged in either of the three layers. Eac... 相似文献
