Abstract

The synthetic array technique has previously been used to provide insight for developing improved microphone array data processing techniques. In recent work, however, it has also been successfully applied to diagnose the source of unexpected (and nonphysical) tones which arose in unsteady computational fluid dynamics (CFD) simulations of hot supersonic jets. The insight obtained from this method has allowed the authors to rapidly arrive at a strategy that greatly improves the results. This success opens up additional areas where the synthetic array technique can find application.
