Stability of a charged spherical layer of a low-viscosity fluid on the surface of a solid core
Abstract
The critical conditions of the onset of Rayleigh instability in a charged fluid film on the surface of a solid spherical core are calculated as a function of the charge magnitude, film thickness, and fluid viscosity. A dispersion expression for capillary waves in a charged layer of a low-viscosity fluid on the surface of a solid core is obtained which constitutes a generalization of a well-known dispersion relation for capillary waves in a charged drop. An expression is also obtained for the attenuation decrement of capillary waves as a function of the charge and fluid layer thickness.
