Droplet characteristics as a function of experimental parameters in electrospray deposition

In this study, the atomization mode and droplet size of an electrostatic atomization system and a system with a ring electrode were compared. The parameters of the ring electrode, namely the outer diameter of the nozzle, nozzle-to-ring distance, and applied voltage, were used to determine the droplet size and atomization characteristics. In addition, the droplet size was compared with those calculated using existing theoretical equations, and the Sauter mean diameter (SMD) of ethanol = a(1 + applied ring/nozzle voltage (RNV))b and SMD of distilled water = a(1 + RNV)b were calculated. These SMDs can be used for determining the nozzle-to-ring/outer diameter ratios up to a maximum range of 10., All data was recorded in real-time and recorded in an Excel file, which was then created in Origin Pro 16 based on the Excel file. Also, the droplet size expression was created using the Origin Pro 16 file., , # Droplet characteristics as a function of experimental parameters in electrospray on deposition process

## README DESCRIPTION

In this experiment, the droplet size equation using experimental parameters is different from the existing droplet size equation using only fluid properties, and the experimental variables are divided into nozzle diameter, nozzle and ring distance, ring diameter, and ring voltage, and the experiment was conducted using ethanol and distilled water, two representative solvents most often used in electrostatic atomization. The flow rate was fixed at 1.5 ml/h to derive the droplet size equation based on the experimental parameters.

For the applied voltage, the applied voltage output from the HVPS was saved in excel in real time for the experiment. For droplet size and distribution, we used spray tech equipment using marlvern's MIE scattering technique to receive data on the DAQ ...
