This project develops the necessary tools and methods to measure H2O absorption spectra
in harsh environments, and calculate temperature and mole fraction from the measured spectra.
Various wavelength-agile sources are designed to obtain absorption spectra. The best
performing wavelength-agile laser source for H2O measurements to date is the Fourier-Domain
Mode-Locking laser. Specific procedures are highlighted to best accommodate the
measurements in the presence of beam steering and thermal emission. A robust method to
calculate temperature and absorber mole fraction is also developed.
Measurements were taken to quantify accuracy in a shock tube and steady burner (used to
stimulate gas turbine conditions). Results from HCCI engine measurements demonstrated the
precision of the measurements. Temperature results greater than 1000 K have been shown to be
biased low. This is a major concern since the main function of the sensor is high temperature
combustion studies. Preliminary studies indicate that using a better database for reference
spectra should improve these high temperature results. |
