Abstract:

The objective of the present program was to study the aerothermochemical structure of laminar premixed and nonpremixed-flames through a non-intrusive experimental determination in reduced and elevated pressure environments, b computational simulation using detailed flame and kinetic codes, and c asymptotic analysis with simplified and reduced mechanisms. Useful theoretical and experimental contributions were made on the determination of the burning rates and flame kinetics of the lower hydrocarbons, on the understanding of the physical and chemical parameters influencing soot formation in diffusion flames, on the identification of the role of kinetics and system non-adiabaticity in flammability limits, and on adiabatic flame stabilization. These results are relevant to the fundamental and practical issues of flame kinetics, turbulent combustion, soot formation, radiative heat transfer, flame extinction, stabilization and flammability, and supersonic combustion. Flammability limit, flame extinction, hydrocarbon combustion, chemical kinetics, flame stabilization, soot formation, turbulent combustion.
