摘要

采用同轴线-圆柱电极系统研究了负电晕放电臭氧的产生，分析了阳极(圆柱)的组成及其半径对负电晕放电臭氧产生的影响。具体来说，三种不同的半径(0.65,0.85和1.1厘米)和两种不同的材料(不锈钢和铝)被用于阳极。臭氧浓度测量使用紫外分光光度计，在放电期间和其熄灭后。实验结果与数值模拟结果相辅相成，采用漂移扩散模型对问题进行了数值模拟，该模型考虑了臭氧在阳极上的分解和焦耳加热的影响。

Ozone generation using negative wire-to-cylinder corona discharge: the influence of anode composition and radius

Ozone generation by negative corona discharge has been investigated using a coaxial wire-cylinder electrode system, and the effect of the composition of the anode (the cylinder) and its radius has been analyzed. Specifically, three different radii (0.65, 0.85 and 1.1 cm) and two different materials (stainless steel and aluminium) have been used for the anode. Ozone concentration was measured using a UV spectrophotometer, both during the electrical discharge and after its extinction. The experimental measurements are complemented with the numerical simulation of the problem using a drift-diffusion model that includes ozone decomposition on the anode and the effect of Joule heating.
