Talk Title: Computational and Experimental Study of Laminar Flames

Abstract: As emissions legislation becomes more restrictive, a detailed understanding of pollutant formation in flames has become even more critical for the design of pollutant abatement strategies and for the preservation of the competitiveness of combustion related industries. It is clear that there will be continuing pressure to lower both NOx emission indices and soot volume fractions in practical combustion devices. This is in response to the toxicological effects of small particles and to the impact, for example, that soot can have on thermal radiation loads in combustors and on turbine blades. Moreover, soot emissions can enhance contrail formation and such "man made" clouds may have an impact ultimately on the Earth's climate. In this talk we discuss our research related to the effects of complex chemistry and detailed transport on the structure and extinction of hydrocarbon flames in coflowing axisymmetric configurations. We have pursued both computational and experimental aspects of the research in parallel on both steady-state and time-dependent systems. The computational work has focused on the application of accurate and efficient numerical methods for the solution of the steady-state and time-dependent boundary value problems describing the various reacting systems. Detailed experimental measurements were performed using two-dimensional imaging techniques. Our goal has been to obtain a more fundamental understanding of the important fluid dynamic and chemical interactions in these flames so that this information can be used effectively in combustion modeling.
