An Investigation into the Physics of Non-Equilibrium Plasmas for Pollution Abatement Applications

摘要-Gundersen CTS-9713275这是一项对极短高压脉冲产生的非平衡等离子体的物理和工程研究，重点是污染缓解应用。该项目结合了调制器设计、高级诊断和复杂的建模，以提供对等离子体反应堆、其基本物理及其应用的基本见解。使用可调谐激光系统的激光诱导荧光(LIF)将被用于由先进电源驱动的反应堆中，以获得包括氮氧化物(NOx)和挥发性有机化合物(VOCs)在内的特定物种的数据。结果将用时间相关的二维混合蒙特卡罗/流体模型来模拟。然后，该模型将用于模拟诸如反应器几何形状、施加电压的幅度、化学添加剂和主体流动参数等参数的影响，以及用于特定应用的反应器设计的结果。

Abstract - Gundersen CTS - 9713275 This is a study of the physics and engineering of non-equilibrium plasmas generated by extremely short high-voltage pulses with an emphasis on pollution-abatement applications. The project combines modulator design, advanced diagnostics, and sophisticated modelling to provide basic insight into the plasma reactors, their underlying physics, and their applications. Laser-induced fluorescence (LIF) using a tunable laser system will be utilized in reactors driven by advanced power sources to obtain data about specific species including nitrogen oxides (NOx) and volatile organic compounds (VOCs). The results will be modelled with a time-dependent two-dimensional hybrid Monte Carlo/fluid model. This model will then be used to simulate the effects of parameters such as reactor geometry, amplitude of the applied voltage, chemical additives, and bulk flow parameters, and the results used in design of reactors for specific applications.
