Noise Source Analysis For Simulated Turbulent Jets, Robert W. Skidmore, Nitin S Dhamankar, Kurt M. Aikens, Gregory Blaisdell

The Summer Undergraduate Research Fellowship (SURF) Symposium

Large Eddy Simulation (LES) is an efficient computational approach to study turbulent flows and has seen increasing application to the study of jet noise. The main challenge of LES has been the realistic simulation of experiments at reasonable cost. Recent LES studies have been realistic enough to gain important insight into jet noise from the large amount of data generated. This study attempts to characterize the sources of noise from a turbulent jet via analysis of the LES results. Three different analysis tools are implemented. The first two are comparable to analyses used on experimental data: two-point cross-correlations between far-field …
