Axisymmetric Bluff Body Turbulent Flow

 

Code name: B2F3
Wind Tunnel Dimension (m): 0.305 * 0.305
Coflow air shroud (m): 0.086 ID, 0.090 OD
Jet Diameter (m): 0.0020
Bluff Body Diameter (m): 0.0500
Fuel mixture: CH4-CO = 50.0%-50.0% (by vol.)
Stoichiometric Mixture Fraction: 0.114
Blowoff velocity (m/s): 103.5
Shroud air velocity (m/s): 25
Wind tunnel air velocity (m/s): 2
Open flame, No enclosure

The following values have been used in calculating the mixture fraction:
Total Mass fraction of Oxygen   atoms in the air stream,  Zo,o = 0.233
Total Mass fraction of Carbon   atoms in the air stream,  Zc,o = 0.0
Total Mass fraction of Hydrogen atoms in the air stream,  Zh,o = 0.0
Total Mass fraction of Oxygen   atoms in the fuel stream, Zo,f = 0.3634
Total Mass fraction of Carbon   atoms in the fuel stream, Zc,f = 0.5450
Total Mass fraction of Hydrogen atoms in the fuel stream, Zh,f = 0.0916


NOTE: The hydorxyl radical is not measured in some selected flames
      presented here because of intereference from flame emission.
      When this is the case the OH values are reported as zero.
