Abstract

Ice accumulation on windward components of the wind turbine can lead to a significant reduction in efficiency and even trigger security incidents. This work introduces a novel three-electrode dual-spark surface dielectric barrier discharge (SDBD), which combines the streamer mode for de-icing by generating heat and the dual-spark mode for ice breaking via shock waves. Firstly, the characteristics in different discharge modes and the discharge mode transition are investigated using electrical and optical diagnostics, enabling reliable control of the discharge modes. Subsequently, the spatiotemporal evolution of aerodynamic performance induced by pulsed dual-spark discharge is examined through schlieren imaging system. The initial shock wave velocity can reach up to 519 m/s. And the shock wave velocity exhibits a characteristic of exponential decay with time, eventually decaying to the speed of sound and propagating outward. And a pronounced enhancement of pressure wave intensity is observed at the interaction region of the two shock waves.

纳秒脉冲三电极双火花SDBD诱导激波的等离子体特性及耦合特性

风力涡轮机迎风部件上的积冰会导致效率显著降低，甚至引发安全事故。本文介绍了一种新型的三电极双火花表面介质阻挡放电（SDBD），它结合了通过产生热量进行除冰的流光模式和通过激波进行破冰的双火花模式。首先，利用光电诊断技术研究了不同放电模式下的放电特性和放电模式转换，实现了对放电模式的可靠控制。随后，通过纹影成像系统研究了脉冲双火花放电对气动性能的时空影响。初始激波速度可达519 m/s。激波速度随时间呈指数衰减，最终衰减到声速并向外传播。在两种激波的相互作用区域，压力波强度有明显的增强。
