A1 - VESSEL
Field of Application:
- Distribution of hydrogen in closed volumes
- Turbulent Combustion in uniform and non-uniform gas mixtures at different initial pressures
- Flame Propagation regime, effect of venting and pre-compression in connecting rooms
- Flame Acceleration and DDT (deflagration-to-detonation-transition), effect of obstacles and multiple, connected compartments with different volumes
- Vented Explosions, jet initiation of Detonations
- Integrity of Mechanical Structures under high pressure loads
Instrumentation:
- Thermocouples (gas temperature)
- Piezoelectric and piezoresistive gauges (pressure)
- Mass spectrometer, gas flow control (gas composition)
- Sonic hydrogen sensors (hydrogen distribution)
- Photodiodes, ion probes (gas velocity)
- Strain gauges (structural deformations)
Technical Details:
- Cylindrical vessel of 98 m^3, internal diameter: 3.3 m, length: 12 m
- Licensed static pressure of 100 bar
- Temperature: ambient
- Gas components: Hydrogen, Air, Nitrogen, Oxygen
- Several vents of diameter up to 800 mm
