摘要

以热力学平衡和化学平衡假设为前提

在求解电弧等离子体统计热力学参数的基本原理的基础上

考虑了粒子激发态的影响

得到精确的粒子配分函数

进而运用德拜模型将等离子体粒子相作用的影响包含在内

从化学平衡方程得到氮气和氩气平衡态电弧等离子体内部粒子成分与温度、气压的函数

并以此计算获得相应的统计热力学参数.利用此方法计算出了不同气压条件下(0.01、0.10、0.30、0.50、1.00 MPa)、不同温度范围内(300～40 000 K)氮气和氩气电弧等离子体热力学参数

并与以往文献中的部分结果进行了对比与分析.结果表明

在15 000 K以内统计热力学参数的计算结果良好

随着温度的继续升高

计算结果产生了误差

误差主要来源于配分函数计算方法和德拜修正带来的计算精度的差异.

Abstract

Taking thermodynamics and chemical equilibrium as a premise

the species excited state's contributions to the precise species partition functions is considered and the Debye model in view of the influence of plasmas species' interactions is utilized. Based on principles of calculating thermodynamic properties of arc plasmas

the species compositions of nitrogen and argon arc plasmas in equilibrium state as a function of temperature and pressure are obtained and the relevant statistic thermodynamic properties are further presented

where the thermodynamic properties of nitrogen and argon arc plasmas under different pressure conditions(0.01

0.10

0.30

0.50 and 1.00 MPa)and in different temperature range(300～ 40 000 K)are demonstrated and compared with previous literatures. It is shown that the statistic thermodynamic properties results in the temperature range of lower than 15 000 K are in good agreement with the recent literatures. However

the differences

which are brought from the adoption of different calculation methods of partition functions and the different calculation accuracy by Debye correction

come out as the temperature further increases. The obtained statistical thermodynamic properties may provide reliable reference data for the further arc plasma research and application.
