Abstract
This paper presents an application of Doak's ``Momentum Potential Theory of Energy Flux carried by Momentum Fluctuations'', extended for analyzing multi-chemical-component and reactive flows. New components, related to the dynamics of the mixtures, are superimposed to the canonical Doak's decomposition in turbulent, acoustic, and thermal momentum fluctuations. The extended model is used here to characterize the thermoacoustic behavior of a bluff-body stabilized premixed flame, represented by Large Eddy Simulation data of the Volvo Test Rig. The main characteristics of the combustion noise are highlighted by combining the results obtained through the model with the Spectral Proper Orthogonal Decomposition.
