N2 - This chapter presents an overview of the detailed measurements of flow, pollutant emissions, and acoustics in model multiple-swirl, partially-premixed flames, and combustors. The chapter discusses the role of partial mixing and swirl on pollutant and noise emissions from aeropropulsion gas-turbine engines. Three-dimensional flow velocity fields using particle image velocimetry (PIV), sound pressure using microphone arrays, and pollutant emissions using gas analyzers are the planned measurements used to investigate the role of partial mixing on emissions. The computational studies of swirling combustor flows employ computational aeroacoustics approaches based on large-eddy simulation (LES) to predict flow, flame, and acoustics features. The chapter summarizes previous work, current objectives, and the technical approach used in aeroacoustics and the emissions studies of swirling combustor flows. Multiple-swirl combustors and trapped-vortex combustors are studied in the chapter with geometries relevant to naval and industrial applications.
