摘要:

利用氮系统的高温热力学函数Cp,m,结合热量计算公式及能量平衡关系,在理论上得到热平衡等离子体射流温度与放电功率和气体流量的定标关系。结果表明,该过程满足相似性原理,射流温度不是功率和流量的一般二元函数,而是比值Peff/f 的一元函数。并对结果进行了相关的分析和讨论,为热等离子体的应用提供了参考数据。

关键词: 热等离子体, 射流温度, 定标关系, 放电功率, 气体流量

Abstract:

With the help of heat balance equation and high temperature thermodynamic function, the calibration relation of jet temperature with discharge power、gas flow rate was obtained for nitrogen thermal plasma. It was shown that the results were agreed with the principle of similarity. The jet temperature was a function of Peff/f, instead of a general two variables function of Peff and f, which were effective discharge power and working gas flow rate, respectively. A related discussion has been given; it will be referable to thermal plasma applications.

Key words: Thermal plasma, Jet temperature, Calibration relation, Discharge power, Gas flow rate
