The Koopman theory, a concept to globally model nonlinear signals by a linear Hamiltonian,
has been at the frontier of fluid mechanics research for the last decade. Wind engineering …

This work augments a Linear-Time-Invariance (LTI) notion to the Koopman analysis, finding
an invariant subspace on which consistent Koopman modes are expanded with fluid …

We develop a method for the prediction of flow fields based on local particle image
velocimetry (PIV) measurement. High spatial resolution can be achieved by focusing PIV on …

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 …

The present work extends the parametric investigation on the sampling nuances of dynamic
mode decomposition (DMD) under Koopman analysis. Through turbulent wakes, the study …

This serial work presents a linear-time-invariance (LTI) notion to the Koopman analysis,
finding consistent and physically meaningful Koopman modes and addressing a long …

Direct numerical simulations are performed for flow past circular cylinders by the lattice
Boltzmann method coupled with immersed moving boundary method. By analyzing the flows …

In this study, the flow mechanisms around wall-mounted structures was numerically
investigated using Large Eddy Simulation (LES). A comparison was made between the …

Fluctuating velocity plays an essential role in tornadic winds and the induced transient
loads, while its characteristics are rarely considered in existing tornado models. Based on …

Existing research on interference effects predominantly focuses on rigid structures.
However, studies based on rigid models tend to overlook the feedback of structural motions …
