Blow-off of swirl flames as well as its mechanism are fundamental issues and attract
continuous attention due to its wide application in modern combustors. This study …

An experimental study on the compact lean premixed flames stabilized on a bluff-body and
swirl burner is performed. The flames are featured with a strengthened Inner Recirculation …

The structure of unconfined lean premixed CH 4/air flames stabilized with an axisymmetric
bluff-body and a swirler was studied for conditions far from and close to blow-off. Blow-off …

In this study, we investigated the H 2-induced transition of confined swirl flames from the “V”
to “M” shape. H 2-enriched lean premixed CH 4/H 2/air flames with H 2 fractions up to 80 …

Flame stabilization in many practical devices is achieved primarily through swirl; however,
the application of swirl to an inverse diffusion flame and its effect on both flame stability and …

ABSTRACT A study of the destabilising effect of self-exited bulk-mode oscillations on the
shape and size of recirculation zones has been carried out in a swirl burner/furnace. Cycle …

The present paper examines the capability of low swirl flows in stabilizing low calorific value
fuels. To such an aim, CO 2 gas is used to adjust the reactivity of CH 4/air mixtures. The …

This paper studies the flame dynamics near lean blowout (LBO) conditions in a stratified
swirl burner. The novel BASIS burner is used and fueled with premixed methane/air mixture …

Lean premixed combustion (LPC) is a promising technology for low-NOx emission, while it
increases the risk of blowoff at the same time. Experiments and Large Eddy Simulations …

Bluff-body and swirl flow are commonly utilized to stabilize diffusion flames in industrial
applications, such as gas turbines, ramjets and furnaces. Flame stabilization mechanisms of …
