Abstract:

An experimental investigation was conducted to examine optical sizing techniques in gas turbine combustors and exhaust augmentor tubes. The two primary objectives of this thesis were to improve the accuracy of optical particle sizing in the combustor and across the augmentor tube, and to verify the improved capabilities with a test series. Multiple wavelength light transmittance and light scattering techniques were used. Particle sizes were found to be .15 to .17 microns in the combustor, increasing in size to .35 to .45 microns in the aft can, and 1.5 to 1.6 microns at the exit of the augmentor tube. A MALVERN 2600 HSD particle sizer was used to verify the accuracy of the T-63 optical system. A number of recommendations for improving the system were discussed. Theses.
