✦ Synopsis
The eigenfrequencies of an oscillating viscous charged liquid drop under surface tension are evaluated by assuming potential flow and by solving the linearized Navier-Stokes equation. The kinetic and dissipation energies of this system are obtained via the inertias and friction coefficients and the angular momentum of the drop is calculated. A discussion of the nature of the viscous flow reveals that: (i) for small viscosity the curls tend to concentrate close to the surface (boundary layer effect); (ii) once having excited the drop, the fluid can come to rest only asymptotically (caused by the curls); and (iii) that the potential flow approximation has only a limited validity.
