中文摘要: 本项目是研究较大空间非平衡态等离子体的产生及其对燃烧过程包括着火和火焰传播的作用机理。研究主要可分为两部分:较大空间稳定非平衡态等离子体的产生及性质,即非平衡态等离子体电子密度和能量分布函数以及激发态粒子密度和分布;各种条件下非平衡态等离子体中存在的电子和其他激发态粒子对燃烧着火及燃烧过程的影响。在实验中利用射频电感和电容两种放电方式实现了在较高压力(大气压或近大气压)和较大空间的点火。通过对非平衡态等离子体产生和性质的数值分析以及激发态粒子对燃烧反应的作用的理论分析,对非平衡态等离子体对燃烧过程的作用机理进行了分析探讨,建立了相应的机理模型。

英文摘要: This project is to study the mechanism of larger spatial non-equilibrium plasma formation and its effect on the combustion and ignition(plasma assisted combustion). Research mainly includes two parts: the generation of a stable larger space non-equilibrium plasma and the characteristics of the non-equilibrium plasma such as electron density and energy distribution function and excited particle density and distributions; under various non-equilibrium conditions, the influence of electrons and other excited particles on the combustion ignition and combustion processes. In the experiments, using two kinds of discharge means (RF inductors and capacitors)to achieve a higher pressure (atmospheric pressure or near atmospheric pressure) and a larger space of ignition. With numerical simulation of the non-equilibrium plasma characteristics and generation process, and theoretical analysis about the effects of excited particles on combustion process, the mechanism of nonequilibrium plasma assisted combustion was discussed
