Numerical Simulation of a Coating Sprayer Capable of Producing Controllable Paint Droplets 2015-01-0737

Lack of a precise control over paint droplets released from current coating sprayers has motivated this study to develop an atomizer capable of generating a uniform flow of mono-dispersed droplets.
In the current study, a numerical investigation based on CFD incorporating volume of fluid (VOF) multiphase model has been developed to capture the interface between air and paint phases for a typical atomizer equipped with piezoelectric actuator. Effects of inlet flow rate and actuator frequency on ejected droplets' characteristics, droplet diameter and their successive spacing are studied in detail. It will be shown that for a determined flow rate of paint, there is an optimum actuator frequency in which droplet size is minimum. Besides, there exists a direct relationship between the inlet paint velocity and obtained optimal actuator frequency.
