This paper presents the results of an experimental investigation into the detailed structure of a gas turbine spray at near-atmospheric pressure and temperature conditions. Airblast atomizer of the prefilming type was tested with water as the spray medium. The characteristics of the spray were examined with a phase Doppler analyzer, a laser diffraction sizer and high speed photography using sheet illumination. The spray studied is found to exhibit an inhomogeneous structure with respect to droplet size, velocity, number density, and ballistics, with implications for the attainment of satisfactory combustion-emissions performance. Characterization of dense, near-field spray regions with laser diagnostics presents a difficult challenge due to the effects of multiple scattering.
