Science fair project
 
Electrostatic air movers have been developed and improved since Hauksbee first noted that a corona discharge causes wind back in 1709.

Inventions have improved that airflow with repelling, attracting, collecting, and other electrodes so that diectional airflows of speeds up to 1700 fpm have been achieved. However, I have seen nothing in the patents or the literature that addresses the use of fluid dynamics to improve intake or exit airflows through the use of nozzle technology.

Here is a sample patent with a tube diameter of 2.5 to 4 cm and length of 3.5 to 8 cm that produces an airflow of 500 fpm. http://adzoe.8m.com/IonAir/us004210847-001.tif http://adzoe.8m.com/IonAir/us004210847-002.tif http://adzoe.8m.com/IonAir/us004210847-003.tif http://adzoe.8m.com/IonAir/us004210847-004.tif

I want to explore what would happen if I improved the inlet and outlet throat and nozzle respectively. But I have no idea how to begin. Can anyone help me? I am in the 8th grade, and in the past have won blue ribbons at different levels for producing the first homemade aerogels and for studying high tech polymers as pool cue tips. I want to broaden my horizon this year with this research. Thank you.
