| Abstract: | The natural frequencies of a liquid drop, a liquid around a rigid center core and a liquid in a spherical tank have been investigated in the present paper. For the spherical systems, the analytical solution is given, while for the nonspherical systems, a boundary element method was adopted to solve the problems numerically. |
