辉光放电等离子体对气压变化的响应特性
Response Regularity Between Glow Discharge Plasma and Static Pressure Change
摘要
Abstract
The frequency response of traditional measurement instruments cannot break through MHz level. In order to investigate more complicate unsteady flow, the new theory needs to be developed, where the field of glow discharge (GD) has the potential to obtain ultra-high frequency response. Before the high-frequency AC drive experiment, the coupling relationship of GD plasma and air pressure was analyzed. Thus, a direct voltage was applied to the electrodes in the experiment, to explore the response regularity between discharge voltage and a wide range of static pressure (0.5~1.0 atmosphere pressure). The results demonstrate that for a spacing of 50μm with the current increasing from 3mA to 4.5mA, the calibrated curves between discharge voltage and pressure decrease monotonically, working in the “abnormal” GD regime. On the contrary, the calibrated curves for a spacing of 250μm with the current increasing from 2mA to 3.5mA, increase monotonically, working in the“sub-normal”GD regime.关键词
