电晕放电诱导风（CDIW）已广泛应用于食品和半导体工业的生产线以及静电除尘器等室内设备。一些臭氧不可避免地被排放，对人类的呼吸系统和肺功能构成严重的健康风险。在这项工作中，一个绿色的电晕放电与增强风力发电的针到缸放电结构，证明了使用一个简单的浸涂方法将碳纳米管（CNT）的不锈钢针的放电电极。与传统的放电电极相比，没有CNT装饰，CDIW的速度大大提高，起始电压降低，能量转换效率大大提高，产生的臭氧浓度大大降低，使这种简单的CNT装饰方法成为绿色电晕放电系统的有前途的候选人。此外，改善性能的几个影响因素进行了讨论数学和现象学，提供了一个洞察电晕放电和风力发电。
Corona discharge-induced wind (CDIW) has been widely utilized in production lines in the food and semiconductor industries and in indoor devices such as electrostatic precipitators. Some ozone is inevitably emitted, posing serious health risks to respiratory system and lung function of a human being. In this work, a greener corona discharge with enhanced wind generation for a needle-to-cylinder discharge structure is demonstrated using a simple dip-coating method to attach carbon nanotubes (CNTs) to the discharge electrode of a stainless steel needle. Compared with a conventional discharge electrode without CNT decoration, the velocity of the CDIW is greatly enhanced, the onset voltage is lowered, the energy conversion efficiency is greatly improved and the concentration of generated ozone is much reduced, making this easy method of CNT decoration a promising candidate for greener corona discharge systems. In addition, several impact factors for improved performance are discussed mathematically and phenomenologically, providing an insight into the corona discharge and wind generation.
