Abstract
An experimental study was performed to produce fine liquid droplets using the electrohydrodynamic atomization.
The mode of electrohydrodynamic atomization depended on the flow rate of liquid, the inner diameter of the nozzle, the distance between the nozzle tip and the ground electrode, the shape of ground electrode, and applied high voltage. This work was performed to explore the experimental analysis for the flow pattern visualization of droplets and relations between applying voltage and the behaviors of liquid atomization.
The uniform drops with different sizes can be obtained at the inception of the spindle mode by charge the flow rate and electric field. Also, the drop size increased when the flow rate was raised for the spindle mode. The whipping motion occurred beyond 6kV and corona started to take effect.
