A3 - VESSEL

A3-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, Detonations

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)

Technical Details:

  • Cylindrical vessel of 33 m^3, internal diameter: 2.5 m, height: 8 m
  • Licensed static pressure of 60 bar
  • Temperature: ambient
  • Gas components: Hydrogen, Air, Nitrogen, Oxygen
  • Several vents of different sizes
  • Internal volume can be divided into several joint rooms with different volumes
  • Regular obstacle grids can be inserted
  • A3-Vessel can be connected with other vessels, e.g. the A1-Vessel
