摘要
笔者在已研制的壁稳电弧等离子体发生器基础上,改进了阳极结构、加置Laval喷管,建立了一套可长期连续运行的高稳定性电弧等离子体超声速喷管流动装置,超声速电弧射流的不稳定度为1%(纯氩)和3%(氮氩),电弧射流具有很好的稳定性、再现性和对称性。测量表明:超声速电弧射流的电子温度沿流动方向呈现出波浪形周期升降的变化规律。
On the basis of the wall-stabilized arc plasma generator we have developed an arc plasma supersonic nozzle flow device with high stability and long life by impoving the anode structure and adding a Laval nozzle. The stability of spectral intensity for supersonic arcjet is 1% (Ar) and 3% (N_2 & Ar), and the arcjet has high stability, reproducibility and good axisymmetry. The results show that the electron temperature of supersonic arcjet rises and falls periodically along with the flow direction.
