了解电离物质和中性粒子之间的相互作用是发现它们对自然现象影响的先决条件。其中一种现象是电风,它被认为是由于弱电离气体系统中的带电粒子-中性耦合而发生的,但这种机制仍然不清楚。在这里,我们报告的直接证据表明,电风是由带电粒子的阻力作为从电子/离子到中性粒子的动量转移的结果所产生的电流体动力引起的。该模型实验是基于脉冲等离子体射流作为源的弱电离气体中产生的氦气在大气压下使用纹影摄影。研究在不同的放电参数的氦气流轨迹允许一个区分流光传播或空间电荷漂移的影响,导致电风,以及确定的作用,电子和(正)离子在风力发电。电动风的机制仍不清楚。在这里,作者报告了电风是由带电粒子拖曳产生的电流体动力引起的证据,作为动量转移到中性粒子的结果。
Understanding the interactions between ionized matter and neutral particles is a prerequisite for discovering their impact on natural phenomena. One such phenomenon is the electric wind, which supposedly occurs due to the charged particle–neutral coupling in systems of weakly ionized gases, but this mechanism remains unclear. Here, we report direct evidence that electric wind is caused by an electrohydrodynamic force generated by the charged particle drag as a result of the momentum transfer from electrons/ions to neutrals. The model experiment is based on a pulsed plasma jet as a source of weakly ionized gases generated in the helium gas at atmospheric pressure using Schlieren photography. Studying the helium gas flow trajectories at different discharge parameters allows one to distinguish between the effects of streamer propagation or space charge drift causing the electric wind as well as to determine the role of electrons and (positive) ions in wind generation. The electric wind mechanism remains unclear. Here, the authors report evidence that electric wind is caused by an electrohydrodynamic force generated by charged particle drag as a result of momentum transfer to neutral particles.
