| Abstract: | Forced oscillation of both the liquid layer around a sphere and the two liquids in a spherical container is investigated in the present paper. Using spheric functions and Galerkin's method, analytical solutions of the problems are obtained. The results show that the oscillation of the liquid free surface or the interface of the liquids cannot be excited by the translational excitation of the rigid body, which means that the liquids move in drop or bubble style. |
