Chemical kinetics and concentrations of an equilibrium ionized nitrogen-water mixture
Résumé
This paper describes a contribution to the investigation of changes in plasma ionisation rates, caused by water injection. Concentrations were computed., assuming the existence of a state of chemical equilibrium in a mixture of perfect gases consisting of nitrogen water with 0.0001-1 mixture ratios. The most recent data on the 43 chemical species investigated were used. Temperatures raged from 1500 to 6000°K, pressures from l0 to 10 4 Pa. Comparison with pure nitrogen plasma in identical temperature and pressure conditions revealed over-and de-ionization zones which are dependent on mixture ratio, among other factors. Computations required an adaptation of the Brinkley method, due to plasma neutrality and also to the selection o! water injections, which involves a specific ratio of two chemical elements. These computations were used for predicting chemical changes induced by chemical kinetics in such plasmas. 0ne result in a classification of chemical reactions In order of significance, leading to prediction of possible freezes, which is necessary to investigate actual cases of water injection.
