Electrohydrodynamic interactions of droplets

Initially, there is an attraction. However, as they get closer, they cross over since they are misaligned. The line of center is moving away from the field direction, causing them to cross over into the repulsive region and start separating. This is another example where there will be no coalescence.

The last case of the interaction of identical droplets is the one where you have very conducting droplets. In this case, the electrohydrodynamic flow is very weak since its scale is one over the Conductivity ratio. Here, the dominant interaction is the dielectrophoretic interaction, where dipole-dipole interactions prevail.
