97696 - Applications of Spectral Proper Orthogonal Decomposition in Flow and Acoustics Analysis
Spectral Proper Orthogonal Decomposition (SPOD) is the form of proper orthogonal decomposition performed in the frequency domain. It is capable of sifting frequency contents from large data sets and preserving and revealing structures dependent on frequency. In this research, SPOD analysis is performed on flow/structure interaction problems as well as nozzle jet turbulent flow to reconstruct select modes of the spectral data to observe energy-containing structures for flow-induced acoustic analysis. The reconstructed flow is shown to preserve important structures in the time domain which demonstrates that extraction of flow structures using SPOD can be properly mapped back to the physical time domain.
