Abstract: This paper examines and compares the commonly used machine learning algorithms in their performance in interpolation and extrapolation of flame describing function (FDFs), based on experimental and simulation data. Algorithm ...

Abstract: The intrinsic thermoacoustic (ITA) feedbackloop constitutes a coupling between flow, flame and acoustics that does not involve the natural acoustic modes of the system. One recent study showed that ITA modes in annular ...

Abstract: Thermoacoustic properties of can-annular combustors are commonly investigated by means of single-can test-rigs. To obtain representative results, it is crucial to mimic can–can coupling present in the full engine. However, ...

Abstract: The estimation of flame transfer functions (FTF) from time series data generated by large eddy simulation (LES) via system identification (SI) is an important element of thermoacoustic analysis. A continuous time series ...

Abstract: Thermoacoustic systems can exhibit selfexcited instabilities of two nature, namely cavity modes or intrinsic thermoacoustic (ITA) modes. In heavyduty landbased gas turbines with canannular combustors, the crosstalk between ...
