Self-similarity of spanwise rotational motions’ population trends in decelerating open-channel flow
Theoretical and Applied Mechanics Letters, 2022 Decelerating open-channel flow is a type of flow that gradually moves forward with decreasing velocity and increasing water depth. Although all flow parameters change along the streamwise direction, previous studies have revealed that these parameters ...

Structure and Branching of Unstable Modes in a Swirling Flow
Mathematics, 2021 Swirling has a significant effect on the main characteristics of flow and can lead to its fundamental restructuring. On the flow axis, a stagnation point with zero velocity is possible, behind which a return flow zone is formed.

Secondary flow and streamwise vortices in three-dimensional staggered wavy-wall turbulence
Flow, 2023 The present paper simplifies the naturally formed dunes (riverbeds) as large-scale three-dimensional staggered wavy walls to investigate the features of the accompanying secondary flows and streamwise vortices via large-eddy simulation.

Coherent Lagrangian swirls among submesoscale motions [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance The detection of vortices in geophysical flows is important because of their role in global circulation and transport. The recent theory of elliptic Lagrangian coherent structures has shown that long-lived, coherent material eddies exhibiting no filamentation can be extracted from altimetry-derived surface velocities associated ...

Push/Pull Inequality Based High-Speed On-Chip Mixer Enhanced by Wettability
Micromachines, 2020 In this paper, a high-speed on-chip mixer using two effects is proposed, i.e., push/pull inequality and wettability. Push/pull inequality and wettability are effective for generating a rotational fluid motion in the chamber and for enhancing the ...

Large-Eddy Simulation of Particle Diffusion in a Particle-laden Swirling Jet
Journal of Fluid Science and Technology, 2008 Large-eddy simulations (LES) are applied to particle-laden swirling jets, and effect of the swirl on particle dispersion is investigated. The trajectories of all particles are individually pursued with a Lagrangian method.
