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 …

Thermoacoustic combustion instability is one of the most challenging operational issues in
several high-performance, low-emissions combustion technologies, including gas turbines …

This article concerns the flame dynamics of a bluff body stabilized turbulent premixed flame
as it approaches lean blowoff. Time resolved chemiluminescence imaging along with …

The structure of unconfined lean premixed methane–air flames stabilized on an
axisymmetric bluff body has been examined for conditions increasingly closer to blow-off …

The wake characteristics of bluff-body-stabilized flames are a strong function of the density
ratio across the flame and the relative offset between the flame and shear layer. This paper …

Flame-acoustic interactions are witnessed in the context of combustion instability in gas
turbine combustors and other propulsion devices, such as rockets, besides confined …

The increasing computational capacity in recent years has spurred the growing use of
combustion Large Eddy Simulation (LES) for engineering applications. The modeling of the …

In this article we report on an experimental investigation of a bluff-body stabilized lean
premixed flame subjected to different levels of free stream turbulence intensities (4, 14, 24 …

The turbine-based combined cycle (TBCC) engine, as a hypersonic air-breathing propulsion
system, involves the transition between multiple bypasses during flight. During the transition …

An air jet cooling method is adopted to reduce the temperature of the trailing edge wall of a
bluff-body flameholder. The added cooling air jets would rebuild the flow field and reduce …
