| Experiment ID
| GexCon3D-Corner Test 02, Test 22 and Test 66
|
| Short Description
| Explosion experiments with hydrogen were carried out in a 50 litre 3D-array of pipes (l = 0.368 m, diameter and pitch varies, see figure below). Ignition in closed corner. Gas concentrations ER=0.94 (test 02), 1.01 (test 22) and 0.97 (test 66). Thin polyethylene sheets keep gas inside array prior to ignition.
|
| What phenomena were studied
| Effect of blockage ratio for 3D flame propagation.
|
| What phenomena / effects can be studied
| Ability of prediction tool to take into account flame interaction with geometries of varying complexity.
|
| Instrumentation
| Pressure measurement in 4 locations (see sketch below), at positions from corner (mm): Mon1=(1, 43, 43), Mon2=(1,175, 315), Mon3=(265,1,11) and Mon4=(350, 350, 1).
|
| Test variables
| Cylinder diameter and pitch (in other tests more variables are varied)
|
| Data description / Data completeness
| All pressure 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 illustrates well the significance of repeated obstacles to 3D flame acceleration
|
| Relevance to the project purposes
| Should be highly relevant (same tests with nitrogen dilution will be applied in Mitigation workpackage).
