ntsa
Nonlinear time-series analysis of dynamical systems from a single long trajectory: Lyapunov exponents, delay-embedding analysis, and classification of the dynamical regime (fixed point, limit cycle, quasiperiodicity, chaos), with diagnostic figures for each case. Works with any model following the dynamodels protocol.
dynamodels
Dynamical-system models with history tracking and pluggable integrators. Currently includes Van der Pol, Rijke, annular thermoacoustics, Kuramoto–Sivashinsky, Lorenz 63 and Lorenz 96.
Data
A real-time digital twin of azimuthal thermoacoustic instabilities
Acoustic pressure data from an annular combustor, recorded by four microphones at 0°, 60°, 120° and 240°, for four equivalence ratios between 0.4875 and 0.575 at a constant power of 6 kW. Originally created by Indlekofer et al. (2022); also used by the tutorials in real-time-bias-aware-DA.
