  • ISF-5 other flame 1: Delft Adelaide flame

    Delft flame

    Dimensions: Nozzle diameter = 6 mm; Primary air annulus diameter = 45 mm

    Main jet: Natural gas (approx. 81% CH4, 14% N2)

    Pilot: The pilot burns a premixture of C2H2/H2/air.

    Flow Conditions: Ujet=21.9 m/s, Uann=4.4 m/s, Ucoflow=0.3 m/s

    Scalar Measurements in the base of the flame: Raman/Rayleigh/LIF measurements of F, T, major species, CO, OH, and NO were obtained in the TDF lab at Sandia. Accuracy of some species measurements in some locations is limited by high levels of fluorescence interference from soot precursors. CARS temperature measurements and OH PLIF imaging, performed at TU Delft, have also been reported for this flame. Time resolved OH PLIF imaging, using the system at Lund University, has also been done. References are in the documentation file.
