Abstract :
The system of electrohydrodynamics equations consists of two blocks: equations of electrochemistry of liquid dielectrics, describing the passage of electrical current in a liquid with the ionic mechanism of conductivity in the absence of the interaction of ions with a liquid and of hydrodynamics equations, describing the movement of charged liquid in an electrical field. As a rule, it is necessary, that the electrical force is enclosed in the whole liquid. In liquid dielectrics the relation between neutral and charged components is equal to 106 -1010 therefore there is the question about the validity of this rule for a liquid consisting mainly of neutral molecules. In work on electrohydrodynamics the mechanism of transfer of a pulse from charged components to neutral components considered the friction of ions in a liquid. However, this mechanism does not explain how one ion entrains together with self 1010 molecules and more neutral molecules. A study of electrohydrodynamic currents has shown, that the speed of currents much exceeds the speed of ionic drift, and that the ion does not move with respect to environmental molecules and that it can be considered as “frozen” in the liquid
