一个简单的分析流体动力学模型开发的蒸发电子冷却在低压衰减等离子体和比较的二维模拟和实验数据的特定情况下的氩气。测量的电子温度和密度的发展完全再现从头算模型和模拟。此外，它示出，在晚余辉热化的电子发生耦合到离子流体通过库仑碰撞在足够高的电子密度，而不是通过耦合到中性背景。
A simple analytical fluid dynamic model is developed for evaporative electron cooling in a low-pressure decaying plasma and compared to a two-dimensional simulation and experimental data for the particular case of argon. Measured electron temperature and density developments are fully reproduced by the ab initio model and the simulation. Further, it is shown that in the late afterglow thermalization of electrons occurs by coupling to the ion fluid via Coulomb collisions at sufficiently high electron densities and not by coupling to the neutral background.
