Title Toward Active Control of Noise from Hot Supersonic Jets.
Publication Date Nov 2012
Media Count 122p
Personal Author N. E. Murray
Abstract Enhancements to the NCPA PIV seeding system were completed and PIV measurements were acquired on the jet centerline. Auburn supported a Plenopic PIV measurement of the jet. UT Austin submitted an abstract to the 2013 AIAA Aeroacoustics meeting discussing evaluation of noise source indicators. UT Austin submitted a manuscript to JFM on nonlinear distortion of the acoustic waveforms. CRAFT Tech made significant progress on completing the LES simulations and making the data available to the group. CRAFT Tech has made advancements in their beamforming framework. Finally, NCPA hosted ONR (B. Henderson), NASA (J. Bridges), and NAVAIR (A. Aubert) for a site visit.
