Combustion, Explosion and Shock Waves Aims and scope

Abstract

The possibility of reducing the concentration of nitrogen oxides and HNOx-group components with simultaneous shortening of the reaction-zone length during combustion of hydrogen-air mixtures in a supersonic flow behind an oblique shock wave by introducing NH3, CH4, and C2H6 additives into the mixture is analyzed. A numerical study shows that a small (up to 5%) amount of these additives substantially changes the combustion kinetics behind the shock-wave front, shortens the flame length, and diminishes the NO and NO2 content in the combustion products.
