Acoustic source indicators using LES in a fully expanded and heated supersonic jet. Fievet, R., Tinney, C. E., Murray, N. E., Lyons, G., & Panickar, P. Volume 19th AIAA/CEAS Aeroacoustics Conference, AIAA Paper 2013-2093. Berlin, Germany, 2013.

A Large Eddy Simulation of a fully expanded heated supersonic jet flow is examined using acoustic source indicators based on simplification to the Lighthill tensor. This is done in an effort to explore the utility of such methods in defining a rationalized indicator that would help guide future experiments using high-speed PIV, and the accuracy of this rational approach is determined by a detailed comparison with the full Lighthill source term. Finally a wave-number frequency analysis is performed along the mixing layer in order to identify areas of acoustic efficiency, and investigate the importance of the local convective speed of the large-scale structures.
