The sloshing problem for, a spherical tank partially filled with liquid is analysed in this paper. The study is based on the goveming, equations of fluid dynamics and the Euler's equations of systems with the influences of tank off-centering, fluid vortices and the Coriolis' acceleration on the motion states of the systems taken into consideration. In the study, we adopt the concept of uniform vortex motion of fluid generalized by Pfeiffer and apply the boundary element method (BEM) to the calculation of the natural frequence and the velocity field of the liquid sloshing. The motion characteristics of the flow-solid spinning system is then analysed.
