One Approach to Kinetic Modeling of Combustion in Gaseous Composite Fuels

摘要

Combustion of gaseous composite fuels is normally modeled using either (a) macrokinetic formulations or (b) with detailed account of the complex kinetics of chain- branching reactions using a huge standard database. Approache (a), requiring the use of some experimental data obtained in some specific conditions, can describe the system behavior under the above conditions, but is inapplicable for its prediction under other conditions. At the same time, the use of approach (b) not always affords elucidating the role of individual reactions over a wide range of process conditions. In order to eliminate the above drawbacks, in this communication we suggest a novel approach to kinetic modeling of combustion in gaseous composite fuels, using the combustion of hydrogen and methane as illustrative examples.
