Abstract
An experimental investigation was conducted to examine the effects of fuel-air ratio, fuel additives, fuel composition and inlet air temperature on particle sizes in a gas turbine combustor and augmentor tube. Equipment improvements led to validation of two optical sizing techniques, three-wavelength light transmittance and three-angle forward light scattering. Generally, data obtained agreed well with results of earlier investigations. Particle size variations within the combustor due to changing variables were documented. Effects of changing variables were dependent on inlet conditions and station. Fuel-air ratio had no effect on combustor or augmentor tube exhaust particle size. Raising inlet air temperature did not significantly alter particle size within the combustor. The smoke suppressant, ferrocene, did not affect particle size uniformly within the combustor but significantly reduced the augmentor exhaust particle size, especially when combined with an increase in inlet air temperature.
