Determination of laminar flame speed of methane-air flames at subatmospheric conditions using the cone method and CH* emission
Experimental measurements of laminar fl ame speed for premixed methane-air fl ames were carried out for different equivalence ratios at subatmospheric conditions, 852 mbar and 298 K. The fl ames were obtained using a rectangular port burner with a water cooler system necessary to maintain the temperature of the mixture constant. An ICCD camera was used to capture chemiluminescence emitted by OH...
متن کاملStructure of partially premixed n-heptane–air counterflow flames
To avoid the complexities associated with the droplet/vapor transport and nonuniform evaporation processes, a fundamental investigation of liquid fuel combustion in idealized configurations is very useful. An experimental–computational investigation of prevaporized n-heptane nonpremixed and partially premixed flames established in a counterflow burner is described. There is a general agreement ...
متن کاملNOx emissions in n-heptane/air partially premixed flames
NOx emissions in n-heptane/air partially premixed flames (PPFs) in a counter-flow configuration have been investigated. The flame is computed using a detailed mechanism that combines the Held’s mechanism for n-heptane and the Li and Williams’ mechanism for NOx. The combined mechanism contains 54 species and 327 reactions. Based on a detailed analysis, dominant mechanisms responsible for NOx for...
متن کاملChemical Kinetic Uncertainty Minimization through Laminar Flame Speeds of Mixtures of Air with C1-C4-Hydrocarbons
Performing high-fidelity simulations of complex reacting flows requires that the uncertainties associated with predictions of fundamental flame properties are characterized and minimized. Although the kinetics of C1-C4 hydrocarbon flames have been studied extensively in numerous past investigations, notable uncertainties exist. In the present study, the types of hydrocarbon fuels with the great...
متن کاملOlefin Chemistry in a Premixed n-Heptane Flame
ion reactions reach their maximum rates, however, in the high-temperature region, where thermal decomposition reactions are also most active. Formation and Consumption of Other Olefins. Despite the model-dependent differences in reactions of heptene isomers, the chemistry of other olefins is very similar for all three mechanisms, especially for larger olefins. Reactions that involve oxygenated ...
