Abstract :
We observe that the intensity of water vapour absorption lines in a combustion system containing a diffusion flame is highly dependent on the air flow rate. This implies that the recorded signal originates from (lower temperature) water vapour outside the volume of the flame. Seeding the flame enables water to be used as a fuel region marker.
