| 摘 要： | 用把碱金属（Na）加入到空气尾流中进行数值模拟的方法,研究了碱金属引射对高超声速尾流化学动力学和电子密度的影响。采用的化学反应模型为包括O2、N2、O、N、NO、NO＋、Na 、Na、O2-及e-的10组元模型。计算结果表明,碱金属引射,使尾流电子数密度增加1～3个量级。计算结果与文献中的数据符合较好。

| Abstract: | This paper studies the effects on chemical kinetics and electron number density ofinjecting alkaline metal into hypersonic wakes. These effects are obtained through numericallysimulating populated airwake by sodium injection. A ten-specie model is used as chemical reactionmodel, including the species O2. N2. N. O. NO. Na. NO . Na . O2 and e-. The simulated results showthat the effect on electron number density of injecting sodium into wakes is significant, electronnumber density in wakes increases about 1-3 orders. The simulated results are good agreement withthe results in references. |
