| Experiment ID
| GexCon MOGELEG channel (exact Test ID will be provided later):
Empty channel (ER=0.75, 1.00, 1.25), Two baffles (ER=1.00)
|
| Short Description
| Vented hydrogen explosions in a 1.44m x 0.30m x 0.30m channel on a table without or with 2 baffles (B2, B4) of 5 cm height and full (30 cm width) at location 0.48m and 0.96m from inner wall. Ignition centrally at the inner end. Concentration variation provided for the empty channel.
|
| What phenomena were studied
| Venting, external explosion, effect of baffles on flame acceleration, effect of variation in H2 concentration.
|
| What phenomena / effects can be studied
| Ability of prediction tool to take into account flame acceleration across baffles, concentration variations, external explosion effects in connection to venting.
|
| Instrumentation
| Pressure measurement in 4 locations (see sketch below), 3 at rear wall P1=(0.13m,0.299m,0.06m), P2=(0.61m,0.299m,0.06m), P3=(1.095m,0.299m,0.06m) and one outside vent P4=(1.68m,0.21m,0.001m). Ionisation gap measurements were also carried out, but these seemed less reliable.
|
| Test variables
| Geometry is varied (zero or two baffles) and gas concentration is varied (empty channel)
|
| Data description / Data completeness
| All pressure result in digital form
|
| Data availability
| Results owned by GexCon and sponsors Norsk Hydro and Statoil
|
| Source of data / Reference
| Technical Report: GexCon-03-F46201-2-rev01 (confidential)
|
| Why were chosen
| Tests show the effect of external explosion, variation in gas concentration and geometry (baffles)
|
| Relevance to the project purposes
| Should be highly relevant, will act as reference tests for mitigation SBEP tests with nitrogen dilution.
