- Abstract
- Knowledge of reactions occuring in hydrocarbon flames has been improved in recent years. Non-intrusive laser spectroscopic studies of flames and other experiments indicate that reactions in flame fronts of hydrocarbons are of a complex branched-chain type, involving short-lived free radicals which strongly influence the reactions in succeeding links to the chain. However, reactions in postflame, and especially in fuel-rich regions in flames, are still not well understood. As combustion processes involve complex interactions of chemical reactions, with transport and convection, the simulation requires considerable computational efforts and thus has to be restricted to relatively simple cases.
