Theories of Turbulent Combustion in High-Speed Flows.

Abstract

Computational and asymptotic analyses were completed for the structures of wet carbon monoxide flames. Both premixed flames and diffusion flames were considered. It was established that hydrogen containing species affect burning velocities and extinction limits of these flames down to hydrogen concentrations of about one part per million. Reduced chemistry was derived for these flames in the vicinity of this limit as well as above and below it. In particular, useful one-step descriptions were obtained. The results can be applied to determining flammability limits and to predicting influences of water hydrogen addition to dry carbon monoxide systems.
