In this contribution, an overview of the progress in design enhanced FLOX® burner is given. A fuel flexible concept was developed to fulfill requirements modern gas turbines: high specific power density, turbine inlet temperature, and low NOx emissions. The basis for research work numerical simulation. With focus on pollutant emissions, a detailed chemical kinetic mechanism used calculations. novel mixing control concept, called HiPerMix®, its application are presented. view desired...
The thermoacoustic coupling caused by dynamic flow/flame interactions was investigated in a gas-turbine model combustor using high-repetition-rate measurements of the three-component velocity field, OH laser-induced fluorescence, and OH* chemiluminescence. Three fuel-lean, swirl-stabilized flames were investigated, each which underwent self-excited pulsations. most energetic flow structure at condition helical vortex core that circumscribed frequency independent acoustics. Resolving...
An experimental analysis of confined premixed turbulent methane/air and hydrogen/air jet flames is presented. A generic lab scale burner for high-velocity preheated jets equipped with an optical combustion chamber was designed set up. The size operating conditions were configured to enable flame stabilization by recirculation hot products. geometry the rectangular confinement off-center positioning nozzle chosen resemble one a FLOX®-based combustor. arrangement caused formation pronounced...
Sudden changes of flame shape are an undesired, yet poorly understood feature swirl combustors used in gas turbines. The present work studies transition mechanisms a bistable turbulent turbine model combustor, which alternates intermittently between attached V-form and lifted M-form. Time-resolved velocity fields two-dimensional structures were measured simultaneously using high-speed stereo-particle image velocimetry (PIV) planar laser-induced fluorescence OH (OH-PLIF) at 10 kHz. data...
