摘要：

Reactions of NOx and O-3 in jet plume in a low pressure condition were investigated experimentally and numerically. Experiments have been performed in a vacuum chamber, where a low pressure mercury lamp is settled to produce O-3. The ambient gas in the chamber is mixture of 43ppm O-3 and dry air (21% O-2 and 79% N-2). 10.1% NO gas is injected into the chamber, which is diluted by N-x. Reaction amount of NO and O-3 is estimated by measurements of NO2 concentration in plume by LIF method at several points. In addition to experiments, numerical simulations of reactive flow in the same condition have been conducted to investigate reactions in the jet plume in detail. Sensitivity analysis of O-3 concentration on reaction sets was also performed to identify the reaction. As results, reaction mechanism of NOx and O-3 in stratospheric condition and reaction zone in jet plume were identified.
