An Experimental Investigation of Soot Size and Flow Fields in a Gas Turbine Engine Augmentor Tube,

Abstract

An instrumented augmentor tube was constructed and used to obtain velocity and temperature profile measurements as a function of augmentor inlet to gas generator nozzle spacing for use in Phoenics computer code validation. Additionally, optical particle size measurement instrumentation in the form of a three wavelength transmission device and a two forward-angle scattering device using a helium-neon laser was designed, constructed and used for determining the effects of the augmentor flow on the change in soot size across the length. Various smoke suppressant fuel additives were also evaluated for their effect on the soot size changes across the augmentor tube length. The initial tests indicated that particle size increased significantly across the augmentor tube length. Keywords: Soot sizing; and Velocity flow fields.
