INTERACTION OF HELIUM AND ARGON PLASMA JETS ARRAYS

We discuss results from computational investigations of the properties of jets arrays operated in He and Ar. He or Ar is flowing through the tubes of the jets into ambient humid air. We show that jet-jet interactions primarily depend on the properties of plasma forming gas through the tubes. For the helium array, the jets at edges of the array tend to divert while for Ar array plasma propagates more directionally.223-22

Streamer properties of pulsed corona discharge in water

Pulsed discharges in water are investigated to obtain knowledge of fundamental aspects of their behavior. The electrical energy dissipated in one pulse is measured with a calorimetric method to be 80 mJ. From photographs detailed information on streamer structure is obtained. In a gap of 20 mm at a pulse voltage of 20 kV the average length of the streamer in tap water is 5 mm, in deionized water it is 11 mm. The number of streamers is higher in tap water. The propagation velocity of the streamers is determined using photomultipliers and is in the order of 106 mis
