Flow of Gas-Particle Mixtures.

This report outlines studies conducted to characterize the flow of a gas-particle mixture in an axisymmetric jet including the characterization of particle interactions with shock waves formed in the jet in compressible flow. The measurements made include profiles of axial and radial velocity components of the particles and turbulence characteristics of the flow. Flow visualization was used to measure particle concentration and the structure of the shock waves. Samples extracted from the flow provide the particle size distribution in the jet. These studies are needed because of the lack of a sufficiently detailed understanding of these flows, particularly particle-shock interactions, to verify existing computational techniques.
