DETO-78

DETO-78

Detonation tube is constituted of a cylindrical tube of around 6 m long. It is equipped with several diagnostics to study the dynamic parameters of gaseous detonations (Detonation speed, pressure, detonation cell size) and the Deflagration to Detonation Transition a well as the Shock to Detonation transition.

Dimensions :

  • Length 6 m
  • Internal diameter: 78 mm

Pressure / Temperature :

  • 70 bar / 100°C

Operations at this facility began in 2000 for various research projects such as Detonation, Deflagration to Detonation Transition a well as the Shock to Detonation transition and Auto-ignition.
