摘要：
Molecular dynamics simulations are used to study the aggregation dynamics of water-in-oil emulsion droplets under an electric field, and to analyze the effects of electric field strength, type, droplet position, and ionic concentration on their kinematic properties. The best droplet aggregation is observed at E = 0.03V/& Aring; for DC field condition, and E = 0.045V/& Aring; - 80ps for rectangular AC field condition. The rectangular alternating current (AC) field is able to merge the droplets farther away from the center of mass, but the two fields are not able to merge when the angle between the center of mass of the droplets and the electric field force is >= 35.54 degrees. For different ion concentrations, t(40N) < t(20N) < t(60N) < t(0N) in the DC field and t(20N) < t(40N) < t(0N) < t(60N) in the rectangular AC field, and for the same ion concentration, the rectangular AC field takes longer time to merge.
