Abstract

Laser-Induced Incandescence studies of graphite aerosols show that great care has to be taken in interpreting Laser-Induced Incandescence (LII) data from gas turbine exhausts. In principle, particle volume fraction, information on particle size, chemical composition, and physical and chemical properties of the exhaust gas is obtainable by LII without the need for a physical probe in the exhaust. However, much about the way in which laser heated particles interact with exhaust gases has yet to be discovered.
