Turbulent Mixing and Combustion.

Abstract

This report covers the work on gas-particle flow performed during the 1973-1974 contract period. Some previous work, which was published during this period, is briefly reviewed. The main effort was directed toward a study of gas-particle jets injected into a cross flow of clean gas. Photographs of the jets were obtained, and penetration of the jet centerline was correlated with the ratio of the momentum flux of the jet to that of the cross stream, and the distance from the injection point. The loading ratio (particle flow rate/gas flow rate) was 25 for these experiments. Results for lower loading ratios were obtained by a parallel study under different sponsorship. The results and their relationship to the few data available in the literature are discussed. A brief assessment is made for the mean free path for particle-particle collisions in two intersecting gas-particle jets. An extensive review of gas-particle flow was prepared with partial support by this contract, and plans for a future experimental study of a recirculating flow are outlined.
