Toward Active Control of Noise from Hot Supersonic Jets

Abstract

Significant progress has been made on WBS 1.0 and 2.0 items. The MHz PIV system has arrived at NCPA and successfully passed initial system check-out. The near-field microphone array has been built and tested in the UT Austin facility. The specific nozzle hardware to be used for the program has been identified, and mean profile measurements have been completed at the NCPA. CRAFT Tech has completed LES computations of one of the configurations of interest. Graduate students are heavily involved in the activities of each of the academic institutions. The plan for completion of the experimental data collection has been laid out to be completed by the end of the current academic year.
