Structure of Model Gas Flames in Nitramines

Abstract

The purpose of this paper is to summarize the current status of studies we have undertaken of model gas phase flames associated with the combustion of nitramine based solid rocket propellants. These studies consist of measurements of the structure of stable and unstable species concentration profiles and temperature in laminar, premixed, flat flames of fuel Nitrogen Oxide mixtures at low pressure. The experimental measurements are then compared to calculations of the concentration profiles using a one dimensional flame code which models the transport processes and chemistry of the flame. The transport processes include species diffusion and thermal conduction through the flame and the chemistry is modeled by a detailed chemical kinetic reaction mechanism. The flames which have been studied thus far are supplied with Methane, CH20 or CO as fuel and NO2, N20 or O2 as oxidizer. The overall characteristics of the flames are presented in the paper and the preliminary conclusions of the flame modeling are discussed. Keywords: Formaldihyde; Carbon monoxide; Nitrogen dioxide; Nitrous oxide; Oxygen; Diagnosis general.
