The characteristics of nanosecond-pulsed dielectric barrier discharge (nSDBD) in an anti-icing configuration is studied. The mechanisms and energy characteristics of the nSDBD-based plasma-assisted anti-icing are analyzed using a numerical model and existing experimental data. Two-dimensional simulations based on PASSKEy (PArallel Streamer Solver with KinEtics) code are conducted. The code couples a self-consistent fluid model with detailed kinetics, an efficient photo-ionization model, Euler equations and a heat transfer equation for solid materials. The results of icing wind tunnel experiments conducted by two groups are analyzed together. The reduced electric field and the electron density are examined for high-voltage pulses with 800 ns and 20 ns width. The ‘merge’ of counter-propagating surface streamers with the same polarity is numerically observed under high-voltage amplitude. The effects of gas heating and solid heating in time scales of one pulse and one duty cycle are...

基于纳秒脉冲介质阻挡放电的等离子体辅助除冰：建模和机理分析

研究了防冰结构中纳秒脉冲介电势垒放电（nSDBD）的特性。使用数值模型和现有的实验数据分析了基于nSDBD的等离子体辅助除冰的机理和能量特性。进行了基于PASSKEy（具有KinEtics的PArallel Streamer Solver）代码的二维仿真。该代码将自洽的流体模型与详细的动力学，有效的光电离模型，欧拉方程和固体材料的传热方程耦合在一起。一起分析了两组的结冰风洞实验的结果。对于宽度为800 ns和宽度为20 ns的高压脉冲，将检查减小的电场和电子密度。在高压振幅下，在数值上观察到具有相同极性的反向传播的表面拖缆的“合并”。气体加热和固体加热在一个脉冲和一个占空比的时间范围内的影响是...
