Ion wind effect on flame

http://archive.iypt.org/iypt_book/2011_3_Bouncing_flame_Iran_RMN_HA_RA_v3.pdf Ion wind, ionic wind, corona wind or electric wind is the airflow 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.

WebThe underlying mechanism of the flame tilting based on an ionic wind effect is discussed later. AtVDC= ±4 kV, SF+ is extinguished because the flame is highly stretched (by ionic wind) toward SF–[SM 2], while SF–once again leans toward the burnt wire, without any dripping of molten PE. http://gram.eng.uci.edu/~ddunnran/presentations_pub/caltech_05.pdf phonics threshold score 2022 https://fjbielefeld.com
