THE MIXING OF ELECTRICALLY-CHARGED DROPLETS BETWEEN AND WITHIN ELECTROHYDRODYNAMIC FINE SPRAYS

The results of experiments conducted to characterize droplet motion wi thin electrohydro-dynamic fine sprays are examined in the context of p roviding information on the mixing of electrically-charged droplets. T wo cases are considered: one involving droplet mixing between two elec trohydrodynamic fine sprays, and the other droplet mixing within a sin gle electrohydrodynamic fine spray. The results collectively support t hat droplet mixing can be enhanced by relatively simple means, such as increasing the charge density of the spray, decreasing the separation distance between two sprays, or locally modifying the applied electri c field within the spray.
