Grad Seminar: Unsupervised learning for coherent structure identification in turbulent channel flow
Abstract
Coherent structures (CS), i.e., regions of flowing fluid that exhibit significant spatio-temporal coherence, have long been observed in turbulent fluid flow. These CS offer an opportunity to gain insights on fluid behaviour by bypassing the non-linear complexities associated with turbulent flows. Historically, the identification of CS in turbulent flows has involved using manual thresholds to label regions of interest.
