摘要

振动激发分子在等离子体过程中起着重要的作用。数值计算了常压干燥空气(80% N2, 20% O2)环境下二维点对平面流的传播和振动动力学。计算得到的流线平均流速和流线通道半径等特性与实验结果吻合较好。计算表明,N2的振动温度高于O2,且两者的空间分布不同。

Two-dimensional simulation of streamer discharge including the vibrationally excited molecules effects
The vibrationally excited molecules play an important role in the plasma process. We numerically calculate the two-dimensional point-to-plane streamer propagation and the vibrational kinetics in atmospheric pressure dry-air (80% N2, 20% O2) environment. The calculated streamer discharge characteristics, such as the mean streamer velocity and the streamer channel radius, show good agreement with an experimentally obtained results. The calculation shows that vibrational temperature for N2 is higher than for O2 and these two temperature have a different spatial distribution.
