Fuel 33,2% H2 + 22,1% CH4 + 44,7% N2 Exit Velocity 42,15 m/s Reynolds number 15200 Temperature of fuel gas and co-flowing air approx. 295 K Ambient pressure during the measurements 953 mbar Visible flame length 650 - 700 mm
Radial profiles at x/D=5, 10, 20, 40, 60, and 80.Additionally, at x/D=2.5, 30, 50, 70, 100, and 120 measurements have been performed on the flame axis.
Number of samples at each measuring location: 400 (exception: 500 single shots at x/D=2.5, r=0).
This flame was also investigated by Raman/Rayleigh/LIF techniques at the Sandia National Laboratories and the data are available in the internet for download [18].
LDA measurements were performed at the Technical University of Darmstadt and are documented in [12]. For further information please contact Prof. A. Dreizler [13].
