Available in PDF, EPUB and Kindle. Book excerpt: Reduced Order Models (ROMs) and Computational Fluid Dynamics (CFD) codes are tools used to predict the extinction of flames behind bluff bodies. Accurate prediction of these models and codes is predicated on their validation with experimental data. This paper describes detailed experiments to obtain validation data for bluff body stabilized flames over a wide range of conditions. Included are non-reacting data from CFD and LDV, lean blowout and high speed images for three different flame holders. In our previous paper (Kiel 2006) it was asserted that the large vortices were a major driver of extinction. Those assertions are further supported here. It is concluded that the vortex dynamics and not geometry is the dominant mechanism for bluff body flame extinction. This conclusion is supported by the lean blowout data, by the high speed images and reference data from NACA.

Available in PDF, EPUB and Kindle. Book excerpt: This paper is the first in a series of papers studying the behavior of bluff body stabilized flames. In this research a combination of Laser Doppler Velocimetry (LDV), and High Speed Imaging are used to investigate these flames. LDV data taken over several non-combusting operating conditions detail the recirculation zone behind the bluff body as well as the effect of inlet conditions on the Karman Street vortex shedding that occurs. High speed images of combustion and equivalence ratio taken at blow out agree with assertions made by Ozawa (1971) and Zukoski (1957) on the transitional nature of the flame from "laminar" to "turbulent" at a Reynolds number of around 15,000. Lean blow out also correlate very well when using the correlation parameter set down by Dezubay (1950). Finally, high speed images also support assertions by Mehta and Soteriou (2003) Erickson et al. (2006) that under certain conditions Karman Street vortex shedding is not suppressed by momentum and baroclinic effects and are present in the flame near lean blowout.
