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…
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%…
Explorative gradient method for active drag reduction of the fluidic pinball and slanted Ahmed body
Yiqing Li, Wenshi Cui, Qing Jia +4
We address a challenge of active flow control: the optimization of many actuation parameters guaranteeing fast convergence and avoiding suboptimal local minima. This challenge is a…
Machine Learning for Fluid Mechanics
Steven Brunton, Bernd Noack, Petros Koumoutsakos
The field of fluid mechanics is rapidly advancing, driven by unprecedented volumes of data from field measurements, experiments and large-scale simulations at multiple spatiotempor…
