Route to Chaos in the Fluidic Pinball
Nan Deng, Luc R. Pastur, Marek Morzyński +1
The fluidic pinball has been recently proposed as an attractive and effective flow configuration for exploring machine learning fluid flow control. In this contribution, we focus o…
Reduced-order modeling of the fluidic pinball
Luc R. Pastur, Nan Deng, Marek Morzyński +1
The fluidic pinball is a geometrically simple flow configuration with three rotating cylinders on the vertex of an equilateral triangle. Yet, it remains physically rich enough to h…
Locally linear embedding for transient cylinder wakes
Arthur Ehlert, Christian N. Nayeri, Marek Morzynski +1
Reduced-order representations of an ensemble of cylinder wake transients are investigated. Locally linear embedding identifies a two-dimensional manifold with a maximum error of 1%…
Low-order model for successive bifurcations of the fluidic pinball
Nan Deng, Bernd R. Noack, Marek Morzynski +1
We propose the first least-order Galerkin model of an incompressible flow undergoing two successive supercritical bifurcations of Hopf and pitchfork type. A key enabler is a mean-f…
Unstable Periodically Forced Navier-Stokes Solutions---Towards Nonlinear First-Principle Reduced-Order Modeling of Actuator Performance
Marek Morzynski, Wojciech Szeliga, Bernd R. Noack
We advance the computation of physical modal expansions for unsteady incompressible flows. Point of departure is a linearization of the Navier-Stokes equations around its fixed poi…
Metric for attractor overlap
Rishabh Ishar, Eurika Kaiser, Marek Morzynski +6
We present the first general metric for attractor overlap (MAO) facilitating an unsupervised comparison of flow data sets. The starting point is two or more attractors, i.e., ensem…
