Different methods for the numerical description of the behavior of a fluid–fluid interface in an electric field are proposed. A variation in the base system of equations for dielectrics and weakly conducting fluids is demonstrated. A deterministic approach to the description of two-phase flows traveling under the effect of an electric field is used. The system of equations proposed by G. A. Ostroumnov is adopted as a basis for a quantitative description of electrohydrodynamic phenomena. The proposed approach is used in numerical simulation of processes that occur in the intra-electrode space of electrodispersers and electrocoalescers in order to optimize their design and attain the maximal effect of separation with minimum energy costs.
