Yifei Zhu, Yun Wu, Jianzhong Li

摘要:

本文提出了一个计算光电离函数和拟合参数的程序,以建立一个有效的光电离模型。该程序对光谱发射强度、光电离产额和吸收系数的乘积进行积分,计算出各气体的光电离函数和混合物的总光电离函数。通过对总光电离函数的拟合,得到了Helmholtz光电离模型的系数。包括由$\rm N_2$、$\rm O_2$、$\rm CO_2$和$\rm H_2O$分子组成的数据库,用户可以修改该数据库。该程序为等离子体流体模型提供了更精确的光电离函数和源项。

英文摘要:

A program to compute photo-ionization functions and fitting parameters for an efficient photo-ionization model is presented. The code integrates the product of spectrum emission intensity, the photo-ionization yield and the absorption coefficient to calculate the photo-ionization function of each gas and the total photo-ionization function of the mixture. The coefficients of Helmholtz photo-ionization model is obtained by fitting the total photo-ionization function. A database consisting $\rm N_2$, $\rm O_2$, $\rm CO_2$ and $\rm H_2O$ molecules are included and can be modified by the users. The program provides more accurate photo-ionization functions and source terms for plasma fluid models.
