Categorization of Thermoacoustic Modes in an Ideal Resonator with Phasor Diagrams
Kah Joon Yong, Camilo F. Silva, Guillaume J. J. Fournier +1
A recent study (Yong, Silva, and Polifke, Combust. Flame 228 (2021)) proposed the use of phasor diagrams to categorize marginally stable modes in an ideal resonator with a compact,…
Modeling of the nonlinear flame response of a Bunsen-type flame via multi-layer perceptron
Nilam Tathawadekar, Nguyen Anh Khoa Doan, Camilo F. Silva +1
This paper demonstrates the ability of neural networks to reliably learn the nonlinear flame response of a laminar premixed flame, while carrying out only one unsteady CFD simulati…
Incomplete to complete multiphysics forecasting -- a hybrid approach for learning unknown phenomena
Nilam Tathawadekar, Nguyen Anh Khoa Doan, Camilo F. Silva +1
Modeling complex dynamical systems with only partial knowledge of their physical mechanisms is a crucial problem across all scientific and engineering disciplines. Purely data-driv…
Degenerate perturbation theory in thermoacoustics: high-order sensitivities and exceptional points
Alessandro Orchini, Luca Magri, Camilo F. Silva +2
In this study, we connect concepts that have been recently developed in thermoacoustics, specifically, (i) high-order spectral perturbation theory, (ii) symmetry induced degenerate…
Exceptional points in the thermoacoustic spectrum
Georg A. Mensah, Luca Magri, Camilo F. Silva +2
Exceptional points are found in the spectrum of a prototypical thermoacoustic system as the parameters of the flame transfer function are varied. At these points, two eigenvalues a…
