Ion wind
Charged-particle flow due to high electrostatic potential / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about ionic wind?
Summarize this article for a 10 year old
Ion wind, ionic wind, corona wind or electric wind is the airflow of charged particles induced by electrostatic forces linked to corona discharge arising at the tips of some sharp conductors (such as points or blades) subjected to high voltage relative to ground. Ion wind is an electrohydrodynamic phenomenon. Ion wind generators can also be considered electrohydrodynamic thrusters.
The term "ionic wind" is considered a misnomer due to misconceptions that only positive and negative ions were primarily involved in the phenomenon. A 2018 study found that electrons play a larger role than negative ions during the negative voltage period. As a result, the term "electric wind" has been suggested as a more accurate terminology.[1]
This phenomenon is now used in an MIT ionic wind plane, the first solid-state plane, developed in 2018.
