Abstract

Abstract: To investigate the flow fields and combustion characteristics of triple swirlers in confined zones, experimental and numerical investigations are conducted into triple swirlers with different structures of tertiary holes. Meanwhile, the characteristics of two typical swirling flow fields (namely, dome-attached and conical structure swirling flow) and their effects on flame shapes and combustion performance are analyzed. The results indicate that changing the structures of tertiary holes can result in significant changes in the flow field from dome-attached to conical structure swirling flow. When the tertiary hole is 30°, the higher turbulence kinetic energy of the swirler can enhance the fuel atomization quality, and the dome-attached large-sized recirculation zone is beneficial to fuel diffusion and uniform distribution in the primary zone, both of which can improve the ignition and Lean Blow-Out (LBO) characteristics of the combustor. However, it will lead to higher liner wall temperature.

Key words: triple swirlers, dome-attached swirling flow, conical structure swirling flow, flame shape, combustion, confined zones
