SBEP V4 (See D57, pp. 35 - 36)

Comments to the table (download documents: HD-Tab.pdf, H2jet.eps, shadow.eps. Keyword SBEP-V4. They have generic title 'Specifications of V4 Document [1,2,3]'):

Nozzle diameter, d, is internal orifice diameter Distance from the nozzle,
x, is a distance to the transverse cross-section where concentration and velocity profiles were measured (see H2jet.eps file)
Pressure, p, is a pressure measurement at the closest to the nozzle position

Mass flow rate was measured by two sensors (Prandtl and Coriolis) Injection time is a time between opening and cut-off of the valve

Transverse concentration and velocity: YES means that we have data on [H2] and velocity distribution for steady-state regime; NO means that we only have [H2] and velocity measurements at axial jet position against time.

Shadow means that we have or not shadow pictures like that shown in the file attached (shadow.eps)

In order of priorities we recommend you four sets (shown in the table HD-Tab.pdf):
No 1: Ø1 mm; p = 100 bar; tests HD 31-34; tests HDH4 with shadow at 180 bar (complete data with [H2] and velocity distribution with axial time dependence of [H2] and velocity + shadow)
No 2: Ø0.75 mm; p = 208 bar; tests HDH3; (only data with axial time dependence of [H2] and velocity + shadow)
No 3: Ø0.25 mm; p = 160 bar; tests HD 22-24; tests HDH0 and HDH1 with shadow at 100 and 240 bar (complete data with [H2] and velocity distribution with axial time dependence of [H2] and velocity + 2 shadows)
No 4: Ø1 mm; p = 196 bar; tests HDH 13; (only data with axial time dependence of [H2] and velocity + shadow)

 

Data to be presented for comparison with the experiments:

  1. Concentration vs. coordinate along longitudinal horizontal axis C(z)
  2. Concentration vs. radial coordinate in horizontal plane C(r)
  3. Concentration vs. time at horizontal axes z C(t)
  4. Gas velocity vs. coordinate along longitudinal horizontal axis C(z)
  5. Gas velocity vs. radial coordinate in horizontal plane C(r)
  6. Gas velocity vs. time at horizontal axes z C(t)
  7. 'Shadow photograph' movie: it has to cover at least first half of jet (0 m < z < 1 m) and time period (0 s < t < 8 s). These data correspond to the experimental ones.
