Disintegration of a charged viscous jet in a high electric field

Abstract

The paper presents the investigation of excitation conditions of both axisymmetric and nonaxisymmetric perturbations of a charged jet under the action of an electric field. The linearized problem is analyzed in terms of the surface frozen charge approximation. The domination regions of these disintegration types are determined as charge-field variables. Attention is mainly paid to the nonaxisymmetric mode leading to the longitudinal splitting in two of the initial jet. Some versions of the jet instability development are considered when this mode is excited in a high electric field. The experimental data on the longitudinal- and combined longitudinal-axisymmetric disintegrations are presented.
