Characterization of Sudden-Expansion Dump Combustor Flowfields.
Abstract
Basic flowfield studies pertinent to an axisymmetric, sudden-expansion dump combustor have been performed under cold flow conditions. These studies have included surface flow visualization, pressure probing, and gas sampling within a representative combustor duct. Flow visualization tests, which were performed using a surface oil flow technique, graphically demonstrated the complex nature of the flow recirculation/reattachment region downstream of the dump station. Detailed measurements of wall static pressure, flow static pressure, and flow total pressure were made for the combustor flowfield. Gas concentration measurements of simulated fuel (argon)/air mixing were made in the combustor duct using a unique on-line, real-time gas sampling/analysis system. The results obtained from this particular research effort have provided additional insight into the complexities of dump combustor flowfields. (Author)
