Simultaneous PIV, OH- and fuel-PLIF measurements in a low swirl stratified turbulent lean premixed flame
Simultaneous OH-, fuel- planar laser induced fluorescence (PLIF) and particle image velocimetry (PIV)measurements were performed in turbulent low-swirl stratified premixed flames. The combined PIV/PLIF images revealed e.g. the fuel distribution, entrainment of ambient air, mixing with the air/fuel stream and the resulting stratification in the trailing edge of the flame. Flame-flow interaction was
