Size and Velocity Distributions of Particles and Droplets in Spray Combustion Systems.

Abstract

This research was concerned with laser/optical techniques for size and velocity measurements of particles and droplets in spray combustion systems. The initial efforts were directed toward a novel method for simultaneous size and velocity measurements of individual particles. A prototype instrument was designed, constructed, calibrated, and successfully applied. Our efforts to verify the performance and accuracy of this diagnostic led to a parallel research effort on the laser diffraction droplet sizing technique. Significant contributions to the calibration and scattering inversion aspects of this technique were made. Contributions to the problem of aerosol characterizations are discussed. Among the papers included in this final report are: Integral Transform for Particle sizing by Near-forward Light Scattering; Non-intrusive Laser-based Particle Diagnostics; Particle Sizing by Optical; Nonimaging techniques; Response Characteristics of Laser Diffraction Size Analyzers--Optical sample volume extent and lens effects; Single Beam Laser Velocimetry in Turbulent Flows; Response Characteristics of the Multiple-ratio, Single-particle Counter; and Developments in Non-Doppler Laser Velocimetry.
