Dynamics of lean blowout of a swirl-stabilized flame in a gas turbine model combustor
Abstract Lean blowout (LBO) of a partially premixed swirl flame is studied using chemiluminescence imaging and simultaneous stereo-PIV and OH-PLIF measurements at repetition rates up to 5 kHz. The… Expand

Abstract A detailed analysis of the flow–flame interactions associated with acoustically coupled heat-release rate fluctuations was performed for a 10 kW, CH4/air, swirl stabilized flame in a gas… Expand
Experimental study of vortex-flame interaction in a gas turbine model combustor
Abstract The interaction of a helical precessing vortex core (PVC) with turbulent swirl flames in a gas turbine model combustor is studied experimentally. The combustor is operated with air and… Expand
