Abstract

In the current investigation, we examine a turbulent, compressible jet flow field at Mach 1.0. In the fully anechoic jet facility at Syracuse University, the flow field is probed in order to measure near-field hydrodynamic pressure, far-field acoustic sound, and near-field velocity. High resolution 10 kHz time-resolved particle image velocimetry (TRPIV) is implemented to gain better insight into the structures formed in the near region of the jet. By exploring those structures present just after the collapse of the potential core, in conjunction with the near and far-field pressure, low-dimensional modeling techniques are implemented in the form of proper orthogonal decomposition (POD). With these low-dimensional models, we seek to gain a better understanding of how jet noise created in the near-field propagates downstream, and how control can be implemented accordingly using such approaches.
