[ATM] synthetic jets

["Don Clement" <clement.focuser@verizon.net>]

Georgia Tech has come up with a method of breaking up thermal boundary
layers by creating an airflow with tiny vortices. Synthetic jets arrays are
created using electromagnetic or piezoelectric drivers vibrating a diaphragm
at 100 to 200 Hz. The drivers look like small loud speakers. There are no
friction parts to the drivers. I was thinking that this technology could
replace fans blowing across the face of mirrors to break up the thermal
boundary layer. see:
