Droplet Sizing Research Program.

Abstract

A three-year program in droplet sizing research has been completed. The major accomplishments include: (1) Establishing the errors and limitations associated with the Visibility technique; (2) Development of two new technique utilizing absolute scattered light; (3) Extension of techniques to submicron particles; (4) Extension of techniques to nonspherical drops; (5) A solid spray diagnostic capability which has been synergistic with many programs from other agencies of the Air Force (AEDC, BMO, Wright-Patterson), the Government and Industry. The new techniques have been applied to the measurement of sprays and solid particles with accuracies better than 10% and dynamic ranges between 10 and 30. Complex bimodal, trimodal and quadramodal distributions have been measured with an accuracy and resolution exceeding all available techniques. Keywords: Particle velocity, Mass flux, Nonintrusive, and Advanced laser diagnostics.
