This thesis investigated the use of three-wavelength light transmission and forward-angle scattered light intensity ratio techniques to determine the effects of fuel additives on particle sizes and mass concentrations in a T-63 combustor and evaluated several improvements to the T-63 diagnostic system. Data from both optical methods indicated an increase in particle size in a range of .06 to .10 microns occurred in the exhaust region when the fuel additive was used, with no change in mass concentration. The two techniques resulted in different measured particle sizes and require further investigation. Current improvements to the T-63 diagnostic apparatus are discussed along with required changes for further testing.
