Data Release 2.0–January 2003
(Includes scalar data for flames C,D,E, and F)
Dimensions: Nozzle diameter = 7.2mm; Pilot diameter = 18.2mm
Main jet: 25% CH4, 75% air; Fstoic = 0.351, Lvis ~ 67d
Reynolds numbers: C-13400, D-22400, E-33600, F-44800
Pilot: The pilot flame burns a premixture of C2H2, H2, air, CO2, and N2 having nominally the same equilibrium composition and enthalpy as CH4/air. The pilot is operated lean, phi = 0.77, and the flow rate is scaled in the four turbulent flames to maintain the pilot at ~6% of the power of the main flame.
Scalar Measurements: Raman/Rayleigh/LIF measurements of F, T, N2, O2, CH4, CO2, H2O, H2, CO, OH, and NO were obtained with a spatial resolution of 0.75 mm. Results include axial profiles in each flame (x/d = 5, 10, 15, … , 80), radial profiles (x/d = 1, 2, 3, 7.5, 15, 30, 45, 60, 75). Averaged results (both Favre and Reynolds averages) and single-shot data are included in the archive.
Velocity Measurements: Two-component LDV measurements were carried out at the Technical University of Darmstadt.
