Mechanisms of Exhaust Pollutants and Plume Formation in Continuous Combustion

Abstract

During this period, emphasis has been placed on the construction, evaluation, and operation of a two-color laser anemometry (LA) system. Detailed velocity and turbulence intensity measurements have also been acquired in a water analog of the opposed jet configuration, and are scheduled for the centerbody configuration. Application of the numerical code to this case was initiated during the present reporting period for both the opposed jet and centerbody configurations, and the results are being checked with the experimental data as they become available. High-speed photography has been employed in both the combustor and hydrodynamic facilities to study the swirl and non-swirl performance of the centerbody configuration, and to optimize the design. Techniques have been developed (dyes in the hydrodynamic system and smoke in the combustor) to visually record the penetration and dynamics of the fuel jet. The NO probe experiments have addressed the effect of potentially resistant materials, and a refined experiment for the introduction of water and low concentrations of hydrocarbons typical of turbine emission has been completed. Data provide guidelines for the materials and temperature limits to employ in the measurement of NO(x).
