摘要：

The paper presents the results of computer simulation of the current-time characteristic (CTC) of a cell with low-conducting liquid. The basis of simulation is the complete set of electrohydrodynamic (EHD) equations. The injection and dissociation mechanisms of charge formation as well as field-enhanced dissociation are considered. The simulation is carried out in the needle-plane electrode system. The relation between sections of CTC and stages of EHD flow formation is revealed. The shape of CTC is shown to be dependent on mechanisms of charge formation, the ratio of the initial and steady-state ion concentrations and the mechanisms of charge transport.
