A real-time digital twin of azimuthal thermoacoustic instabilities

This Zenodo repository contains the dataset used in Nóvoa et al (2024). The dataset is also used in the tutorials available on github.com/MagriLab/real-time-bias-aware-DA.git. The dataset was originally created and published in Indlekofer et al (2022) and contains acoustic pressure data in an annular combustor. The pressure is recorded by 4 microphones placed at $\theta=\{0°, 60°, 120°, 240°\}$. There are four files containing the microphone time traces for 4 different equivalence ratios (ER) 0.4875-0.575 (by steps of 0.0250) and constant power 6kW.
