Timescales of dynamic stall development on a vertical-axis wind turbine blade
Sébastien Le Fouest, Daniel Fernex, Karen Mulleners
Vertical-axis wind turbines are great candidates to diversify wind energy technology, but their aerodynamic complexity limits industrial deployment. To improve the efficiency and l…
Cluster-based network modeling -- automated robust modeling of complex dynamical systems
Daniel Fernex, Bernd R. Noack, Richard Semaan
We propose a universal method for data-driven modeling of complex nonlinear dynamics from time-resolved snapshot data without prior knowledge. Complex nonlinear dynamics govern man…
Cluster-based network model
Hao Li, Daniel Fernex, Richard Semaan +3
We propose an automatable data-driven methodology for robust nonlinear reduced-order modelling from time-resolved snapshot data. In the kinematical coarse-graining, the snapshots a…
Actuation response model from sparse data for wall turbulence drag reduction
Daniel Fernex, Richard Semaan, Marian Albers +3
We compute, model, and predict drag reduction of an actuated turbulent boundary layer at a momentum thickness based Reynolds number of Reθ = 1000. The actuation is performed using…
Drag Reduction and Energy Saving by Spanwise Traveling Transversal Surface Waves for Flat Plate Flow
Marian Albers, Pascal S. Meysonnat, Daniel Fernex +3
Wall-resolved large-eddy simulations are performed to study the impact of spanwise traveling transversal surface waves in zero-pressure gradient turbulent boundary layer flow. Eigh…
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…
