Measurements of Gas Turbine Combustor and Engine Augmentor Tube Sooting Characteristics.
Abstract
A methodical investigation was conducted to examine soot particle sizing techniques and data acquisition apparatus so as to better understand soot particle properties in and immediately aft of a typical gas turbine combustor. Three wavelength light transmittance and multiple angle forward light scattering particle sizing techniques were used. The original objectives of this thesis were (1) to modify the existing hardware to better simulate the flow behavior in an actual engine, (2) to obtain accurate particle sizing using a combination of transmittance and scattering measurements within the T-63 combustor, (3) to explore the effects that augmentor tube flow rate has on particle agglomeration and mass concentration, and (4) to reexamine the effects that varied fuel-air ratios have on the exhaust particle mean diameter. Mean particle sizes were found to be between .77 microns and .80 microns at the exit of the augmentor tube. Keywords: Optical sizing of soot; Gas turbine combustors; Exhaust augmentor tubes.
