摘要

本文提出了一种改进的自洽多组分二维等离子体混合模型，用于模拟大气环境下直流正电晕放电。该模型基于等离子体流体力学和化学模型，包括12种27种反应。此外，该模型还考虑了光电离效应。在此模型的基础上，详细研究了动态带电物质生成的体积、放电电流波形、电子温度和电场变化。结果表明，该模型对空气电晕放电的物理特性提供了有价值的认识。

Numerical simulation of DC positive corona discharge under atmospheric environment

This paper presents an improved self-consistent, multi-component and two-dimensional plasma hybrid model for the simulation of DC positive corona discharge under atmospheric environment. The model is based on the plasma hydrodynamics and the chemical modles, it includes 12 species and 27 reactions. Besides, the photoionization effect is also considered in the proposed model. Based on this model, the volume of dynamics charged species generation, the discharge current waveform, electron temperature, and electric field variations are investigated in details. The results indicate that the model provides valuable insights to the physics of air corona discharge.
