Flow control-oriented coherent mode prediction via Grassmann-kNN manifold learning
Hongfu Zhang, Hui Tang, Bernd R. Noack
A data-driven method using Grassmann manifold learning is proposed to identify a low-dimensional actuation manifold for flow-controlled fluid flows. The snapshot flow field are twi…
