大气压宽径向空气等离子体射流装置的设计、实验和仿真研究
|
摘要
大气压空气等离子体射流(空气APPJ)能够在开放的大气环境中产生高活性低温等离子体,在细菌灭活、材料表面处理和生物医学应用等方面有广泛应用前景,但是目前空气放电击穿电压高,放电稳定性较差,射流长度较短、径向尺寸小等限制了它的应用。为了降低放电电压及维持放电稳定性,本文在高压电极上包裹一层介质,设计出一种介质包覆的针-金属喷嘴结构的空气APPJ枪,利用COMSOL的静电场模块对枪体的电学特性进行仿真,研究针尖曲率半径、电极间距以及针电极直径等参数对电势和电场的空间分布的影响,发现针尖曲率半径对于场强最大值有较大影响。据此,选择合适的参数,设计并制备了枪体。该枪在交流驱动下能够稳定放电,APPJ径向尺寸3 mm左右、长度达到17 mm。分析了射流长度、功率和气体温度随气流流速的变化,并与氮气和氩气放电进行了比较,其放电参数与氮气基本相当,与氩气相比,放电功率大,温度高,但射流长且径向尺寸宽,更适合活性反应场合的应用。
Atmospheric pressure air plasma jet(Air APPJ) was modified mainly by coating the shank of tungsten electrode with a dielectric layer to decrease the discharge voltage and increase the discharge stability.The plasma generation was mathematically modeled,numerically simulated with software COMSOL and experimentally evaluated.The influence of the electrode's geometry and alignment,including the exposed tip-apex curvature radius,shank diameter and electrode spacing,on the discharge behavior was investigated for design optimization.The simulated results show that the tip-apex radius has a major impact.The new air APPJ with the optimized tip geometry was tested.As shown in the measured results,the fairly stable APPJ had a diameter of 3 mm and a length of 17 mm.Moreover,the discharge behavior of the newly-designed air APPJ outperforms argon discharge properties,because of higher discharge power/temperature,longer/wider plasma jet and more suitable for application in active reactions.
