Abstract
The relations on the deformable interfaces between movable media in the presence of a surface charge and a double electric layer are derived. The electrohydrodynamic phenomena arising during deformations of media interfaces are studied. The relations derived should be used for describing these phenomena.
The problem of mercury drop pulsations in the electrolyte solution is solved. The solution obtained is proposed to be used for the experimental determination of electrolyte solution concentration as well as physico-chemical characteristics of the mercury-electrolyte solution interface, such as: the surface charge, the potential jump and the differential capacity of an interphase layer.
A physico-mathematical model is proposed, that describes the operation of an electrocapillary transducer. A well coincidence between theoretical and experimental amplitude-frequency characteristics of a transducer is demonstrated.
