摘要: The surface densities of flame fronts in turbulent premixed propane/air flames were determined experimentally. instantaneous visualized using laser induced fluorescence (LIF) OH on two Bunsen type burners 11.2 and 22.4 mm diameters. Non-dimensional turbulence intensity, u′/S L, was varied from 0.84 to 15, the Reynolds number, based integral length scale, 34 467. These are flamelet combustion regime as defined by most recent diagrams. From 100 800 images recorded for each experimental condition. Flame obtained maps progress variable, which is zero reactants unity products. corrected mean direction cosines fronts, had a typical value 0.69 flames. In non-dimensional intensity range up it found that maximum surface...
