The numerical analysis showed that the water droplets trapped onto the hydrophobic titanium dioxide (TiO2) coated electrodes and at 2 mm inter-electrode distance can increase the electric field intensity above 300 kV/m, where droplet rupture takes place. Experimental study showed highest demulsification efficiency of 76% while applying AC voltage of 250 V, frequency of 200 kHz and inter-electrode distance of 4 mm.enCC BY-NC-ND 4.0 (Attribution-NonCommercial-NoDerivatives)https://creativecommons.org/licenses/by-nc-nd/4.0/Water-in-oil emulsionDielectrophoresisDemulsificationHigh frequency alternating current600Artikel/Aufsatzurn:nbn:de:gbv:46-elib88183
