高频激励AC-DBD气体电离区域及电极的温升特性

Temperature Rise Characteristics of Ionzed Gas and Electrode for AC-DBD Under High Frequency

  • 摘要: 介质阻挡放电能够产生电离效应、气动效应和热效应,可以作为飞机防除冰的一种新方式。激励频率是决定交流介质阻挡放电(alternating current dielectric barrier discharge, AC-DBD)温升效果的主要因素之一,但目前还缺乏高频条件研究结果,为此开展AC-DBD在30~55 kHz高频范围的气体电离区域及电极的温升特性实验。研究表明:石墨烯涂层有助于减小金属电极的红外测温误差;高频激励方式可以产生更高的温度,电压峰峰值22 kV、频率50 kHz时气体电离区域温度可至323.27 ℃;气体电离区域及电极的温度均随着电压峰峰值增大而非线性增加,电压处在较高范围时温升斜率更大;气体电离区域及电极的温度均随着激励频率增大而非线性增加,频率较高时具有更大的温升斜率。此研究为介质阻挡放电装置实现更好的防除冰效果提供了一定的参考。

     

    Abstract: Dielectric barrier discharge may produce the ionization effect, the aerodynamic effect and the thermal effect, which can be used as a new way of anti-icing for aircraft. The excitation frequency is one of main factors that affect temperature rise of alternating current dielectric barrier discharge (AC-DBD), however, the research results under high frequency are not widely available in the literature. Consequently, we performed the experiments of temperature rise for ionized gas and electrode of AC-DBD in the frequency range of 30~55 kHz. The results show that graphene coating is helpful to reducing the measurement error of metal electrode via infrared thermometry. The high temperature can be produced under the high frequency, and the temperature of ionized gas can reach 323.27 ℃ when the peak-peak voltage is 22 kV and the frequency is 50 kHz. The temperatures of ionized gas and electrode increase nonlinearly with the rise of voltage, and the temperature rise will quicken at higher voltages. The temperature will increase nonlinearly with the rise of frequency, and the temperature rise will quicken at higher frequency. This study supplies the certain reference for achieving the preferable anti-icing effect by DBD actuator.
