Modelling a droplet moving in an electric field. (English) Zbl 1078.78002

If a droplet is put into a homogeneous electric field, the droplet disturbs the field, the field effects a concentration of charge at the droplet surface and the droplet deforms due to the force density which the disturbed electric field causes on the electric charge. In this case, the droplet suffers a pure deformation without any translation. If, however, the uncharged droplet is put into a slightly inhomogeneous electric field, a translation of whole the droplet may occur. The main purpose of this paper is the calculation of the force and the caused translation of a droplet in a general electric field.
