🌬️ At some points chaos connects. In fluid dynamics Spectral Submanifolds (SSM) are continuations of a spectral subspace of linearized kinetic events near a stationary state such as fixed points, periodic orbits or a quasiperiodic torus. Various model exists of SSM. In this experiment are used two flags of different bending rigidity in different ranges of flow velocities and transient dynamics. The study ought to be the 1st experimentally constructed inertial manifold for a chaotic attractor that shows how SSM-reduced models can identify not only stable fixed points, but also the unstable ones, limit cycles, heteroclinic orbits and even chaotic attractors. The results highlight the infinite-dimensionality of nonlinear and mixed reduced-order models reaching stable stationary equilibrium states. cambridge.org/core/journals/…
