Sandia/TUD Piloted CH4/Air Jet Flames
Data Resease 2.0--January 2003
(Includes scalar data for flames C,D,E, and F)
Sydney Burner Geometry
Dimensions: Nozzle diameter = 7.2mm; Pilot diameter
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.
