APPLICATION OF ULTRASENSITIVE LASER ABSORPTION METHODS IN THE STUDY OF COMBUSTION MECHANISMS
00:00 15-05-2007
In this talk, I will review Intracavity Laser Absorption
Spectroscopy and Cavity Ringdown Laser Absorption Spectroscopy
techniques applied to a study of combustion mechanisms. The use of
ultrasensitive Laser Absorption Methods allowed us to perform in
situ spatial concentration measurements of HCO, 1CH2, OH and CH
radicals in a low-pressure flat methane/air flame, and NH and NH2
in N2O doped low-pressure flat methane/air flame, and compare the
results with model calculations. Understanding the mechanisms of
combustion is of high importance to the mankind. Combustion
processes are largest universal source of energy. At the same time,
combustion processes are largest source of global pollution.
Absolute concentration measurements of intermediate species of
combustion mechanism are necessary both for determination of rate
constants of radical-radical reactions and for better understand-
ing of the chemical mechanisms of combustion. One of the best ways
to improve the understanding of those mechanisms is monitoring in
situ of spatial concentration profiles of different reactive
intermediates followed by comparison of the results with model
calculations
