Calculation of droplet collision frequencies in an electric field acting on a water-in-oil emulsion

To simulate the process of water-oil emulsion breakdown under the influence of an electric field in industrial plants, it is necessary to solve the equation for the droplet size distribution density, for which the droplet collision frequencies are estimated analytically. This paper presents the calculations of the frequencies based on solving the system of motion equations for a large number of droplets. The results obtained are compared with analytical estimates.
