Emulsion Droplet Pair Coalescence under a Direct Current Electric Field

Figure 6

(a) Coalescence led to stable or unstable droplet configurations under an electric field. (b) Schematic of the coalesced droplet stretching and the movement of the point C (θ = 0) at the side end to a new position, C. r represents the radius of the undeformed droplet, and α represents the length of the semimajor axis of the deformed droplet.
