In this study the characteristic of lean‐premixed flames from a rotating double concentric
burner is investigated. We investigate especially on the effect of rotational speed, mixture …

The behvior of premixed flames in a rotating flow field has been investigated using a swirl
type burner, in which a fuel/air mixture is ejected tangentially into a cylindrical combustion …

The characteristic of swirling flames produced by a rotating double concentric burner is
described. The effect of rotational speed, mixture ratio and mixture velocity on the shape …

In normal gravity buoyancy has a substantial impact on flame oscillations, pollutant
emissions and flame stabilization limits and so its influence on flame motions is of practical …

The flame behaviors and velocity fields of unexcited and excited swirling double-concentric
jet flames were experimentally studied. Acoustic excitation was applied to the central fuel jet …

We investigated flame structure and stability characteristics of swirling flames in a natural-
gas-fired experimental burner in which the swirl is generated by the rotating outer pipe of the …

Experimental investigation of a partially premixed flame stabilized in a combination of bluff
body and swirling flowfields is reported. Simultaneous measurement of 2D fuel distribution …

The effects of swirl intensity on non-reacting and reacting flow characteristics in a flat flame
burner (FFB) with four types of swirlers were investigated. Experiments using the PIV method …

The effect of radial distribution of swirl has been examined on the thermal behavior of two
different premixed flames using a double concentric premixed swirl burner. The double …

Lean premixed combustors have a narrow stable combustion range compared with diffusion
combustors and have flashback. Due to production constraints, the combustor does not …
