초록

This study is to discuss simulation results with 51 principal chemical reactions in non-thermal plasma space under atmospheric pressure, and the ambient gas was mainly composed of oxygen and nitrogen molecules. The initial density of O and OH radicals under the ambient temperature of 300K is largely generated in comparison with other higher temperature, and the density of O radical decreased from 20μs according to increase the temperature. The initial density of OH radical seemed to decrease steeply at the initial stage. By increasing the initial density of H2O molecules, O radical's effect was few and the density of OH radical was largely generated about 2 times. In addition, ozone density was increased as increasing the density of O radical, but it was decreased as increasing the density of H2O. In case of the temperature more than 300K, NO2 tend to be removed, but NO was increased than the initial density.
