[HTML][HTML] Spatial prediction of the turbulent unsteady von Kármán vortex street using echo state networks

M Sharifi Ghazijahani, F Heyder, J Schumacher… - Physics of …, 2023 - pubs.aip.org
The spatial prediction of the turbulent flow of the unsteady von Kármán vortex street behind
a cylinder at Re= 1000 is studied. For this, an echo state network (ESN) with 6000 neurons …
