The deicing process and its status characteristics of dual-side pulsed surface dielectric barrier discharge (SDBD) are studied via electro-optical diagnostics, thermal properties, and numerical simulation. Experimental results show that the dual-side pulsed SDBD can remove the glaze ice compared to the traditional pulsed SDBD under the applied pulse voltage of 8 kV and a pulse frequency of 1 kHz. The maximal temperature of dual-side pulsed SDBD reaches 39.5 °C under the discharge time of 800 s, while the maximal temperature of traditional pulsed SDBD is still below ice point about −7.8 °C. Surface temperatures of dual-side pulsed SDBD demonstrate that the SDBD with a gap of 1 mm possesses prospects in deicing. The maximal surface temperature reaches 37.1 °C under the pulse of 8 kV after the discharge time of 90 s. Focusing on the thermal effect, a two-dimensional plasma fluid model is implemented, and the results also indicate that the dual-side pulsed SDBD with a gap of 1 mm produces a highest heat density among the three different configurations. Comparing the spatial-temporal evolutions of plasma on both dielectric sides, primary positive streamer has a longer propagation length of 8.6 mm than the secondary negative streamer, the primary negative streamer, and the secondary positive streamer, which induces a long heat covered area. Four stages of deicing process are analyzed through a series of electrical parameters under different covered ice conditions.

双面脉冲表面介质阻挡放电除冰及状态特性

通过光电诊断、热性能和数值模拟研究了双面脉冲表面介质阻挡放电(SDBD)除冰过程及其状态特征。实验结果表明,在施加脉冲电压8 kV、脉冲频率1 kHz的条件下,与传统脉冲SDBD相比,双面脉冲SDBD能够去除釉冰。在800 s的放电时间下,双面脉冲SDBD的最高温度达到39.5℃,而传统脉冲SDBD的最高温度仍低于冰点约-7.8℃。双面脉冲SDBD的表面温度表明间隙为1 mm的SDBD具有除冰前景。在8 kV脉冲下,放电时间90 s后,最高表面温度达到37.1 °C。着眼于热效应,实现了二维等离子体流体模型,结果还表明,间隙为 1 mm 的双面脉冲 SDBD 在三种不同配置中产生最高的热密度。比较电介质两侧等离子体的时空演化,初级正流光的传播长度比次级负流光、初级负流光和次级正流光的传播长度长8.6毫米,从而产生较长的热覆盖区域。通过不同覆盖冰条件下的一系列电参数分析了除冰过程的四个阶段。
