The volume-of-fluid based numerical method of Berry et al. (J. Computational Physics, 251, pp. 209–222, 2013), for predicting electrokinetic flow of multiphase flow with deformable interfaces, is extended to account for the effect of interfacial charge. The numerical representation of interfacial charge is validated using two simple test cases. Finally, the use of the extended algorithm is demonstrated by simulating the breakup of an unstable charged water drop in air.
