Abstract In this paper, a novel ozone prediction model was developed based on the mechanism of ozone generation in the corona discharge region that ionized region would make oxygen become ozone. The coupled solving equation of electrostatic field and ozone concentration were established, which considered the influence factors of polarity, voltage, current, free diffusion, and gas velocity. A pin-cylinder corona discharge device was used to observe the status of corona discharge and measure the ozone concentration in positive and negative polarity conditions, respectively. Results showed that the corona discharge region in two polarity conditions presented the different status and gave rise to unlike ozone concentration distribution. The novel ozone prediction model in this work was confirmed as an accurate tool to predict the ozone generation and distribution in the fluid domain, and would exert its essential role in the guidance of ESPs design and the control of ozone risk.

一种预测电晕放电区臭氧生成的新模拟方法

摘要 本文根据电晕放电区的臭氧产生机理，即电离区使氧气变成臭氧，建立了一种新的臭氧预测模型。考虑了极性、电压、电流、自由扩散和气体流速的影响因素，建立了静电场与臭氧浓度的耦合求解方程。使用针筒电晕放电装置观察电晕放电状态并分别测量正极和负极条件下的臭氧浓度。结果表明，两种极性条件下的电晕放电区呈现出不同的状态，产生了不同的臭氧浓度分布。
