Determination of the Size Distribution Function for Particles in a Hypersonic Flow Field

Abstract

The mean particle diameter and size distribution function of submicron particulate matter were determined for an Arc-heated, short-duration flow field. From these measurements the particle number density and mass fraction in the flow were also estimated. The experiment provided approximately 10-msec time resolution and yielded the desired information by making use of both angular scattered intensity and degree of polarization measurements. The novel aspects of both the experimental and analytical methods employed are described.
