					                         Assisted Corona Discharges and Ionic Winds
                      Student: Rakshit Tirumala                     Advisors: Dr. Go

OVERVIEW
Alternative cooling technologies that utilize     single corona
ionic winds for application in portable           electrode
electronic devices with small form factors to
replace mechanical fans.


IMPORTANCE
•  Miniaturization of ionic wind blowers to
duct heights of less than 2 mm.
                                                       gate collecting         secondary
•  Reduce the operating potentials to < 2 kV

•  Generate > 0.5 cfm air flows with above
constraints
