Decoupling bi-directional fluid–structure interactions by the Koopman theory: Actualizing one-way subcases and the role of crosswind structure motion

Z Chen, Y Wang, S Wang, H Huang, KT Tse, CY Li… - Physics of …, 2022 - pubs.aip.org
We propose a novel thinking of decoupling bi-directional fluid–structure interactions (bi-FSI)
into simpler mono-directional components for analytical insights. The decoupling aims to …
