The focus of this research is to investigate the process of the generation of electrical charges at the nozzles of sprays. This work will be done in collaboration with an industrial partner, Spraying Systems Company (SSCo), a large international manufacturer of spray products with a well-equipped research lab near the University of Illinois at Chicago. The motivation for the research is to facilitate the commercialization of the electrostatic atomizers for coating and painting applications. Both of these applications would benefit significantly from the ability to control drop trajectories to avoid waste, provide precision deposition, and reduce the spread of hazardous materials. The proposed work aims at providing the understanding needed to achieve these performance characteristics. In addition, a low-cost computational model as a predictive tool for the design of these atomizers is being developed. The proposal includes concurrent studies based on theory, computation and experiments. A successful electrostatic atomizer for non-conducting liquids will provide great advantages in sprays and coatings, which are materials that surround us and we use in everyday life.
