    Abstract

    Liquid sprayed by the electrohydrodynamic (EHD) method is atomized only by electrical forces without additional mechanical energy applied. EHD spraying is an effective method for generating electrically charged aerosol. The effect of liquid viscosities on the spraying process was investigated experimentally for distilled water and ethylene glycol mixtures, with viscosity ranging from 1mPas to about 22mPas. When the viscosity increased the jet diameter and the droplet size decreased in the jet mode of spraying. It was noticed that transition of the spindle mode to the jet mode takes place for lower voltages as the liquid viscosity increases.
