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.

Alternative fuels for aviation are clean (conference talk)
Not only replacement fuels for aviation are compatible with low emission combustors: it is recommended to use these together.
This statement is the synthesis of a literature review combined to the results of the European project called Alfa-Bird. This task was conducted by Jaana Rajamäki from CBOne. Alfa-Bird (2008-2010) was dedicated to alternative fuels for aviation. This study closures our participation to this great project, and our results will be presented at the International Symposium on Air Breathing Engines in South-Korea, September 2013.
