The lean extinction limit is one measure of the stability of combustion systems. Over the past
60 years there have been many papers on the extinction of bluff body flame holders. Early in …

Bluff body stabilization of flames is a commonly employed technique for combustion
applications, such as thrust augmentors. These combustors are usually required to operate …

THE stabilization of a flame in the wake region created downstream of a bluff body
immersed in a high-velocity gas stream is a phenomenon of practical as well as scientific …

This paper overviews the dynamics of bluff body stabilized flames and describes the
phenomenology of the blowoff process. The first section of the paper provides an overview …

This paper considers shear layer flame stabilization with a particular focus on velocity
scaling of blowoff limits. Analysis of the expression for hydrodynamic flame stretch, κ, in a …

This paper compiles and analyzes bluff body stabilized flame blowoff data from the literature.
Many of these studies contain semi-empirical blowoff correlations that are, in essence …

This paper compiles a number of experimental and computational results on the dynamics of
bluff body stabilized flames and proposes a phenomenological explanation of the blowoff …

Experiments have been performed to define the influence of blockage on flame stabilization
by bluff bodies in ducted flow. Flameholders of a particularly simple geometry were studied …

I. Introduction lame instability in practical combustion systems has been a topic of great
interest due to unresolved complexities of the coupling of fluid dynamics, chemical kinetics …

The effects of chemistry and approach turbulence intensity were studied for confined,
turbulent, and premixed bluffbody stabilized methane-air flames. These experiments …
