Abstract
Instantaneous two-dimensional flame structure in turbulent propane-air premixed flames is studied using OH-PLIF (Planer Laser Induced Fluorescence). Turbulence is generated by performed plate. A lean mixture (equivalence ratio : φ=0.60∿0.75) of 175cm/s averaged velocity is selected for experimental condition. Turbulence intensity is about 17cm/s, classified in wrinkled flamelet regime on the Regime diagram. Instantaneous 2-D OH image is visualized to make clear the flame front and OH structure. Results show that cusps on the flame front appeared. As equivalence ratio increases, OH peak distance is larger with the increase the flame front curvature.
