The object of this work is nonstationary ehd-flow modeling in wire-plane electrode system for re- searching processes of volumetric charge forming and evolution, also peculiarities of one,s moving in the interelectrode gap are researched. Equations set, describing modeling process appreciably nonlinear. Final- element modeling package ANSYS was used for this problem solution. Special algorithm was developed. It was realized as a package of programs, based on approximation, that charge is “frozen” in liquid. Results of calculations are presented as velocity vector plot evolution, pressure distributions and ehd-flow traces. Typi- cal peculiarity of ehd-flow is forming of thin charged stream, which cross interelectrode gap.
