Flow stabilization with active hydrodynamic cloaks [PDF]

open access: yes, 2012
We demonstrate that fluid flow cloaking solutions based on active hydrodynamic metamaterials exist for two-dimensional flows past a cylinder in a wide range of Reynolds numbers, up to approximately 200.

Effect of NACA0012 Airfoil Pitching Oscillation on Flow Past a Cylinder

open access: yesEnergies, 2021
The flow past a cylinder is a classical problem in flow physics. In a certain range of Reynolds number, there will be Karman vortex street phenomenon in the wake of a cylinder, which will greatly increase the pressure drag of the cylinder. By controlling

Numerical Investigation on the Effect of Asymmetry of Flow Velocity on the Wake Vortex of Hydrofoils

open access: yesJournal of Marine Science and Engineering, 2022
The Karman vortex street is a common flow phenomenon. In hydraulic machinery, it is usually located downstream of the guide vanes and the runner blades, which reduces hydraulic performance and may also cause fatigue damage to the structure.

Inhomogeneous dominance patterns of competing phytoplankton groups in the wake of an island [PDF]

open access: yesNonlinear Processes in Geophysics, 2010
We investigate the competition between two different functional groups of phytoplankton in the wake of an island close to a coastal upwelling region. We couple a simple biological model with three trophic levels and a hydrodynamic model of a von Kármán ...
