A design method for the electrostatic atomization of liquid aerosols

A design method based on analysing and matching the physical time constants of the electrostatic atomization process in the cone-jet mode is presented. An algorithm is developed whereby the liquid properties are used as a basis for recommending a capillary diameter and a liquid flow rate such that a stable spray will result once appropriate electric field conditions are established. The algorithm also predicts the droplet diameter about which the aerosol is distributed. Experimental results are presented which confirm the design methodology.
