The coherent structures are related to the heat release fluctuations, which are derived from simultaneously acquired OH* chemiluminescence measurements. Two distinct PVC structures are found that are very differently affected by acoustic actuation. As shown in the paper, SPOD provides detailed insight into coherent structures in the swirl flames. In these measurements, we consider externally actuated, as well as natural dynamics and reveal how the natural and actuated modes interact with each other. We analyze high-speed particle image velocimetry (PIV) measurements from flow fields in a combustor at different operation conditions. The actual focus is put on the application to a combustor flow. In this paper, the fundamentals of SPOD are shortly introduced. This new method-called spectral proper orthogonal decomposition (SPOD)-allows for a clearer separation of the dominant mechanisms due to a clean spectral separation of phenomena. The order by which each animal experienced different media was randomized among the seven individuals tested. Only strikes generated by the appendage ipsilateral to the camera were analyzed.

The filter operation embedded in this method allows for continuous fading from the classic POD to the Fourier mode decomposition. saved using Photron FastCam Visualization software (v.3.6.9.0) run on a PC laptop (Gigabyte P34 Geforce GTX 1050). This method is based on the classic proper orthogonal decomposition (POD) extended by a temporal constraint. We present an application of a newly introduced method to analyze the time-resolved experimental data from the flow field of a swirl-stabilized combustor.
