Coupling-induced instability in a ring of thermoacoustic oscillators. [PDF]
Proc Math Phys Eng Sci, 2022 Thermoacoustic instabilities in can-annular combus-tors of stationary gas turbines lead to unstable Bloch modes which appear as rotating acoustic pressure waves along the turbine annulus. The multiscale, multiphysical nature of the full problem makes a detailed analysis challenging.

Bayesian Nonparametric Modeling of Categorical Data for Information Fusion and Causal Inference [PDF]
Entropy, 2018 This paper presents a nonparametric regression model of categorical time series in the setting of conditional tensor factorization and Bayes network. The underlying algorithms are developed to provide a flexible and parsimonious representation for fusion

Energy and AI, 2021 The intermittent nature of operation and unpredictable availability of renewable sources of energy (e.g., wind and solar) would require the combustors in fossil-fuel power plants, sharing the same grid, to operate with large turn-down ratios. This brings

Neural ODE to model and prognose thermoacoustic instability [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2022 Thermoacoustic instability in a reacting flow field is characterized by high amplitude pressure fluctuations driven by a positive coupling between the unsteady heat release rate and the acoustic field of the combustor. In a turbulent flow, the transition of a thermoacoustic system from a state of chaos to periodic oscillations occurs via a state of ...
