Good Vibes Beat Bad Gas
(conference talk, paper GT2015-42377)
10% less fuel consumption versus conventional for the disposal of gases with low heat value. This was the main result of the MethaNull study presented at the ASME Turbo Expo 2015!

The infrared measurement technique at the LPP test rig of the DLR Cologne (Giuliani et al., ECM 2007)
Infrared absorption is specific to alcanes. Thus, with a specific apparatus, one can determine the effectiveness of combined fuel atomisation and vaporisation. In a word, one can cartography the fuel placement.

See, size and seize the flame: the emotion project
Combustion Bay One.e.U. works currently in co-operation with FH Joanneum/Aviation on the development of an embedded optical sensor for real-time monitoring of the flame condition in aeroengine combustors.
This feasibility study is financed by the Take-Off programme from the Austrian Research Promotion Agency (FFG).
The very promising first results will soon be presented at the following conference:

Heat fluctuation measurements in a flame using a lightweight laser method (journal publication)
Monitoring combustion stability with an interferometric method was validated by a team composed of CBOne members, TU Graz staff and of CNRS researchers.
The results are published in the journal "Combustion and Flame".
