The Fast Model for Ionic Wind Simulation

A. Samusenko[1], Yu. Stishkov[1], P. Zhidkova[1]
[1]Saint Petersburg State University, Research and Educational Center “Electrophysics”, St Petersburg, Russia

Ionic wind is the gas flow induced by the corona discharge. Ions produced by corona are accelerated by electric field and transfer their momentum to neutral molecules. Using ionic wind one can convert electric energy to kinetic energy of air flow almost directly. The phenomenon of ionic ... Read More

Propagation of Cathode-Directed Streamer Discharges in Air

Y. Serdyuk[1]
[1]Chalmers University of Technology, Gothenburg, Sweden

Streamers are considered as main cause of electrical breakdown in air at atmospheric pressure. A streamer is an ionization wave propagating in neutral gas which is converted into low-temperature plasma behind its front. A streamer model is based on drift-diffusion approach where space ...
