High Power Microwave Plasma Beam as A Heat Source (Report I) : Microwave Plasmotron in Nitrogen Gas
スポンサーリンク
概要
- 論文の詳細を見る
A 3kW-class microwave plasmotron in nitrogen is investigated. The dimension of the plasma flame becomes 10cm in length and 0.5cm in diameter in a typical operation. The plasma attains a temperature about 6700°K and its density 7×10^<13>cm^<-3> near the hottest part of the plasma. A remarkable spatial nonuniformity of the plasma conductivity is observed. A large gas flow rate (30≤φ≤200l/min) strongly affects the dimension and the energy transfer process of the plasma. The measurement of the plasma impedance gives a qualitative agreement with the rod model of the plasma. Some theoretical discussions are performed on the energy balance problems and compared with the experimental results.
