Laser-Raman Measurements in a Ducted, Two-Stream, Subsonic, H2/Air Combustion Flow

Abstract

The laser-Raman diagnostic technique has been used for investigating a ducted, two-stream, subsonic, H2/air combustion flow with turbulent jet mixing and recirculation. A primary jet of high-velocity air was surrounded by an outer, low-velocity hydrogen stream. The duct-to-inner-nozzle diameter ratio was varied. The ratios were 2 and 10 for the two conditions investigated. The radial distributions of static temperature and species number densities were determined at several axial positions for each test condition.
