N2 - In the present report results of computer processing of videorecording EHD flows in symmetric system of electrodes such as two wires are presented. Field of speeds of two-dimensional EHD flows is restored with high accuracy by means of specially developed package of programs. Visualization of EHD flows represents a challenge, since low conductivity liquids are very sensitive to contaminations. Researches have shown that for visualization of EHD-flows bubbles can be used. Authors have developed special computer program for handling videotapes of two-dimensional EHD-flows, formed by a wire - wire electrodes. The handling is carried out by means of separate current streamlines selection with further recovery of velocity components and acceleration vectors. Results of handling are vector fields of velocities and acceleration, maps of level lines and surface graphs of velocities and acceleration, and also restored streamlines, graphs of acceleration distribution along lines and some integral characteristics, namely consumption of liquid along discretionary selected streamlines of liquid. In the report results of processing of symmetric counter EHD-flows, and also the asymmetrical EHD-flows received by introduction in an initial liquid - transformer oil, the impurity having risén of electron-donor properties are given. The comparative analysis of properties of passers and through EHD flows is presented. The analysis of kinematic and dynamic structure of EHD flows, has confirmed the zoned structure of flows, stated earlier, also in details has allowed to describe a structure of a zone of recombination and character of its transformation at transition from counter EHD flows to through EHD flows. It is shown; that through EHD flows is preferable to using at designing electrohydrodynamic pumps.
