Modelling Study of NO2 Conversion in N2/O2/H2O/CO2 Mixtures %K %X The main objective of this study is to understand the time evolution of the nitrogen dioxide specie in N2/O2/H2O/CO2 mixture gas induced by negative corona discharge at atmospheric pressure. The fundamental chemistry governing NO2 evolution developed in this paper is based on a full set of processes regrouped in one hundred selected chemical reactions involving twenty molecular, excited, atomic, and charged species. The density was calculated using the continuity equation without the diffusion and convective terms. In literature it has generally been emphasized that certain radicals N, O, and O3 influence the NO2 conversion.  In this study, we complete them by analyzing others species such as negative ions and radicals. The results show that the environmental condition rate of NO2 is well affected by the increase of reduced electric field and concentration.   %U https://www.revistacubanadefisica.org/index.php/rcf/article/view?path= %J Revista Cubana de FĂ­sica %0 Journal Article %& 3 %P 4 %V 37 %N 1 %@ 2224-7939 %8 2020-07-15 %7 2020-07-15
