Toward Active Control of Noise from Hot Supersonic Jets

Abstract

The research team made steady progress in many areas during the reporting period. Review and research into the characterization of the noise source continues and is guiding data analysis efforts. CFD solutions were completed and used to generate time-resolved flow data for further analysis to study relevant aeroacoustic sources. Significant progress was made on the development and application of the computational phased array beamforming analysis. Analysis of standard stereo-PIV data acquired in October, 2012, was completed and reduced to generate a database for further study and comparison with other diagnostic efforts.
