Studies on High Pressure and Unsteady Flame Phenomena
Abstract
The objective of the present program was to study the structure and response of laminar premixed and nonpremixed flames with emphases on effects of high pressure, flame/flow unsteadiness, and chemistry. The investigations were conducted through laser-based experimentation, computational simulation with detailed chemistry and transport descriptions, and advanced mathematical analysis. Specific phenomena studied include the steady-state structure, burning rate, and extinction of flames, the response to impulsive and periodic flow field strain rate variations, the development of intrinsic flame front pulsating instability and its relation to extinction, and studies related to the development of detailed and simplified chemical kinetic mechanisms. These results are expected to be useful to the general interests of AFOSR in the fundamental and practical issues of flame dynamics and chemical kinetics, turbulent combustion, soot formation, radiative heat transfer, flame extinction, stabilization, flammability, and supersonic combustion.
