Emulsion Droplet Pair Coalescence under a Direct Current Electric Field
Figure 2
Uniform-sized droplet pair interaction in a uniform DC electric field. (a) (i) Results obtained by Baygents et al. [30]. (ii) Results obtained by our simulation model. The detailed simulation conditions are σin/σout = 2, εin/εout = 8, λ = 1, and Cae = 1. (b) Droplet pair approach at different nondimensionalized time scale obtained from our simulation model and compared with theory [32]. Here, is the initial center-to-center distance normalized by the droplet radius , is an unperturbed external electric field strength, and and are the permittivity and viscosity of the outside liquid, respectively.
