在这项研究中，作者提出了一个数值模型（NM）的应用于萘（C10 H8）通过电离反应在微波空气等离子体炬转化。NM包括一个压力无关的增强电子能量分布函数（EEDF）和截面计算，增强了相移确定的新公式。在此基础上，计算了C10 H8分子的电子密度ne和O2+、O-、C10 H8、N2和O2粒子密度，并预测了C10 H8分子的转化率。预测结果表明，电离对C10 H8分子转化率的影响不超过0.81 × 10- 10%。基于计算的载气各组分（O2、N2和C10 H8）的碰撞截面，作者建议采用R方（COD）参数R2 = 99%的三次多项式近似截面曲线。MW功率在1.75-20 kW范围内增加，电子密度在（0.5-4.5）× 10 ~（12）m ~（-3）范围内增加。最大的电…
In this study, the authors have presented a numeric model (NM) for application to naphthalene (C10H8) conversion via ionization reaction in a microwave air plasma torch. The NM has included a pressure-independent enhanced electron energy distribution function (EEDF) and cross-section calculation, enhanced by a new formula of phase shift determination. Based on the validated NM, electron density ne and O2+, O–, C10H8, N2, and O2 particles densities were calculated, as well as the conversion rate of C10H8 molecules was predicted. The predicted results showed that the ionization impact on C10H8 molecules conversion has not exceeded 0.81 × 10–10%. Based on the calculated collision cross-section of each species (O2, N2, and C10H8) of carrier gas, the authors suggested using cubic polynomial approximations of the cross-section curves with R-Square (COD) parameter R2 = 99%. MW power increasing in the range 1.75–20 kW has raised the electron density in the range (0.5–4.5) × 1012 m–3. The maximal effect of electro...
