High Power Microwave Plasma Beam as a Heat Source (Report III) : Energy Absorption Process
スポンサーリンク
概要
- 論文の詳細を見る
Measurements of the absorbed power to the plasma and of its temperature for various conditions are performed in a 30kW microwave plasmatron. The absorbed power reaches to about 80% of incident one and the plasma temperature in a pyrex tube of 40mm in diameter is about 6400K. By decreasing tube diameter to 20mm it in creases to about 7000K with a strong decrease in plasma diameter. A week dependence of plasma temperature on input power is obtained, while change of gas flow rate gives no effect on all plasma parameters. Analysis of energy absorption process shows a good agreement between experimental and theoretical results when a virtual cold "wall" is considered to exist by a strong helical flow of the gas, which we call "gas wall".
