摘　　要：风力发电机和飞机在低温潮湿环境下运行时存在表面覆冰问题,进而影响装备的正常工作,严重时甚至危害人身财产安全。已有文献发现两电极沿面介质阻挡放电(surface dielectric barrier discharge,SDBD)在除冰方面有潜在的应用前景,但仍存在温升小和效率低等问题。为有效提高SDBD表面温度和除冰效率,该文将一接地电极安装在高压电极同侧,构成三电极SDBD结构,研究三电极脉冲SDBD等离子体特性及除冰过程与效果。结果表明:在相同的放电条件下,与两电极脉冲SDBD相比,三电极脉冲SDBD在放电能量、表面温度、发射光谱强度和除冰效果等方面表现出更为优异的能力。在20kV脉冲电压作用下,13mm间隙的三电极SDBD比两电极SDBD的放电能量增加了约1.95倍,最高温度提高了8℃。数值模拟结果也进一步表明:通过脉冲快速加热,三电极SDBD温升范围广和热量空间分布均匀,在除冰方面有很大的潜力。研究结果可为脉冲放电等离子体除冰及相关应用提供参考。Wind turbine and aircraft operating in low temperature and humid environment are facing icing problems,which will affect the normal operation of equipment.It can also harm the safety of human life and property in serious cases.As a result,many scholars have carried out relevant researches on deicing.It is founded that two-electrode surface dielectric barrier discharge(SDBD)shows potential application prospect,but it still possesses the problem of low temperature rise and low efficiency.In order to effectively improve the surface temperature and deicing efficiency of SDBD,grounding electrode is installed on the same side of the high voltage electrode to form a three-electrode SDBD in this work.Furthermore,the characteristics of plasma and the deicing process and effect of the three-electrode pulsed SDBD are studied.The results show that the three-electrode pulsed SDBD has higher discharge energy,higher surface temperature,higher emission spectrum intensity and better deicing effect than that of the two-electrode pulsed SDBD under the same discharge condition.Compared with two-electrode pulsed SDBD,the discharge energy has increased by 1.95 times and the maximum temperature has increased by 8℃under 20 kV pulse voltage and 13 mm discharge gap of three-electrode pulsed SDBD.The results of numerical simulation also show that the three-electrode pulsed SDBD generates wider temperature rise region and uniform heat distribution than that of the two-electrode pulsed SDBD.The results can provide reference for deicing of discharge plasma and related applications.
