平衡态与非平衡态电弧等离子体微观特性计算研究综述

Review of Microscopic Property Calculation of Equilibrium and Non-Equilibrium Arc Plasma

以SF_6、CO_2、C_3F_8、C_5F_(10)O等气体为主要介质,介绍了近三十年来国内外对平衡态与非平衡态电弧等离子体微观特性计算的研究进展。平衡态等离子体的微观特性研究,以粒子组分、统计热力学参数、输运系数以及混合扩散系数等物性参数计算为主。而非平衡态等离子体的微观特性研究是在量子化学计算理论的支持下,以化学反应和化学反应速率研究为基础,通过建立双温化学动力学模型来描述粒子浓度的时间演化规律。

This paper uses SF6, C02, C3F8, and C5F100 as the main mediums, and reviews the advances of microscopic property calculation of are plasma under equilibrium and non-equilibrium state during the past three decades. The studies of equilibrium arc plasma mainly dedicate to thermophysical properties, including compositions, thermodynamic properties, transport coefficients, and combined diffhsion coefficients. For non- equilibrium arc plasma, the investigation of microscopic properties is based on the quantum chemistry theory to study chemical reactions and their reaction rates, which helps to build the two-temperature chemical kinetic model to describe the rule of particle concentration versus time.
