The high pressure shock tube consists of a long cylindrical vessel (7 m long and 52 mm internal diameter for the driven section). It is equipped with several diagnostics for shock waves characterization, auto-ignition measurements and species monitoring

Dimensions :

  • Driver section: 2 m long, 114 mm internal diameter
  • Driven section: 5 m long, 52 mm internal diameter

Pressure / Temperature :

  • 40 bar / 130°C

 

This facility is operated since 1990 and is dedicated to the measurements of auto-ignition delay times,  High temperature chemistry, soot formation characterization for the validation of detailed and reduced kinetic mechanisms.
