“…In other cases, particles of nearly equal size may pass with approximately the same velocity (Doppler frequency) and phase and may also be accepted. The performance of the PDPA under conditions of two particles passing the sample volume at one time is described in [23].…”

This review of the recent developments in the phase Doppler method provides information on the advances made to the method and delineates some potential error sources. Methods used to eliminate these potential error sources are also discussed. It is shown through comparison to the Lorenz-Mie theory and the GLMT that the geometrical optics theory offers a reliable and efficient computational tool for the analysis of the light scattering with the phase Doppler method. The geometrical optics theory was then used to optimize the measurement parameters in the system designs and a significant reduction in the measurement uncertainty was realized. Limitations on the particle concentrations in which the instrument will operate reliably are also addressed. A brief discussion of the instrumentation and, in particular, the signal processing is presented. The advantages in using the Fourier transform approach are discussed. As a demonstration of the capabilities of the instrument, several performance tests were reviewed and examples of the application to spray combustion and turbulent dispersion of particles are given.

“…In order to make a particle velocity measurement, it is required that only one particle pass through the interferometric probe volume at a time. Sankar et al [68] have shown numerically that if two particles pass through the interferometric probe simultaneously, the superimposed scattered signal from the two particles will result in a signal that is virtually all noise and will not be detected by the electronic processors.…”

Thus, some thesis and dissertation copies are in typewriter fiic^ viiile others m^ be from aiqr type of computer printer.The quality of this reproduction is dependent upon the quality of the copy submitted. Broken or indistinct print, colored or poor quality illustrations and photographs, print bleedthrough, substandard margins, and improper alignment can adversely affect reproduction.In the unlikely event that the author did not send UMI a complete manuscript and there are missing pages, these will be noted. Also, if unauthorized copyright material had to be removed, a note will indicate the deletion.Oversize materials (e.g., maps, drawings, charts) are reproduced by sectioning the original, b^jnning at the upper left-hand comer and continuing from left to right in equal sections with small overlaps. Each original is also photographed in one exposure and is included in reduced form at the back of the book.Photographs included in the original manuscript have been reproduced xerognq)hicalfy in this copy. Higher quality 6" x 9" black and white photographic prints are available for aiqr photographs or illustrations appearing m this copy for an additional charge. Contact UMI directly to order.
