Experimental and Detailed Numerical Studies of Fundamental Flame Properties of Gaseous and Liquid Fuels
Abstract
The main goal of this research is to provide archival experimental data and provide insight into the physical and chemical mechanisms that control various flame phenomena for a wide range of conditions. Fuel type, equivalence ratio, flame temperature, and combustion mode are the parameters considered. The experimental data are important for a number of reasons. First, they constitute a basis for partially validating the combustion chemistry of a large number of fuels ranging from hydrogen to gaseous and liquid hydrocarbons and alcohols. Second, they can be used in order to assess the effect of uncertainties of diffusion coefficients on the prediction of global flame properties. Finally, such data are essential for assessing the reliability of proposed surrogates of realistic fuels, which are of relevance to air-breathing propulsion. The results and findings of this program are of immediate interest to the design and performance of advanced air-breathing propulsion devices. During the reporting period, progress was made in the following: (1) Studies of flame and ignition kinetics of dry synthesis gas mixtures; (3) Assessment of diffusion and kinetics effects on flame ignition; (3) Determination of lean flammability limits of methane/air and propane/air mixtures under engine-like conditions; (4) Determination of ignition and extinction limits of premixed and non-premixed flames for a wide range of jet and gasoline fuels and their surrogates.
