Improving the pneumatic nebulizer by shaping the discharge of the capillary wick

The theory and function of nebulizers is discussed and their performance parameters are reviewed. The possibility of adjusting the wick-draw and atomization by altering the geometry at the top of the capillary tube is considered. A visual experiment using film as the data collection medium was performed, and the results support the hypothesis that the nebulizer's performance can be improved by adjusting the tube's configuration. Further study is suggested that will complement this preliminary qualitative study.
