Electrohydrodynamic formation of single and double emulsions for low interfacial tension multiphase systems within microfluidics

•Flow parameters effect on the stability of EHD-based droplet formation is investigated.•3D computational analysis of the fluid flow and electrical phenomena is provided.•Effects of capillary number and permittivity ratio on the droplet size are studied.•A new double emulsion formation method based on EHD is suggested.
