Prüfstände & Labors

Our test stands allow us to examine reactive flows in various well-designed experiments.

For the experimental studies presently the following test rigs are available:

  • Test rig for operating an enclosed combustor up to 250 kW and 10 bar
  • Test rig for studying auto-ignition under highly turbulent flow conditions; temperatures of the hot oxidizer flow are up to 1350 K
  • Three test rigs for operating atmospheric turbulent flames up to 150 kW
  • Test rig for operating gas-assisted solid fuel combustion
  • 1-cylinder internal combustion engine with optical access
  • Test rig for exhaust gas after treatment
  • High pressure vessel for studying droplet dynamics at trans-critical conditions
  • Various test rigs for the laminar flames

For operating the test rigs, the following infrastructure is employed:

  • Air compressor: Dry air up to 1000 m3/h at 13 bar, electric pre-heating (80 kW) up to 750 K and 540 kg/h at max. 10 bar
  • Natural gas compressor: natural gas up to 40 m3/h at 20 bar or 4 bar
  • Supply for special gases
  • n-heptane supply (1000 l)

The research at the Institute of reactive Flows and Diagnostics is aiming for an improved understanding of the underlying physical and chemical processes. Our comprehensive experimental data serve in addition for validation of numerical simulations. The gallery of photos provides an impression of the diversity of processes that are studied.
