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

Observation of von Karman Vortex Street in an Atomic Superfluid Gas [PDF]
, 2016 We report on the experimental observation of vortex cluster shedding from a moving obstacle in an oblate atomic Bose-Einstein condensate. At low obstacle velocities v above a critical value, vortex clusters consisting of two like-sign vortices are ...

Compact analogs of the models of vortex flows generated by aircraft flight
Авіаційно-космічна техніка та технологія, 2023 The subject of this work is the development of compact analogs of vortex flows models, which are used in the modeling of vortex structures observed during the flight of an aircraft and the motion of a body in a fluid.

Transition in vortex wakes of flow around an elliptic cylinder
Archives of MechanicsTransition in the wake flow around an elliptic cylinder was numerically investigated at Reynolds numbers (Re) ranging from 3 to 200. The cylinder axis ratio (AR) varies from 0.125 to 8, while its angle of attack (AoA) was examined at 30°, 60°, and 90 ...

Advanced Intelligent Systems, Volume 8, Issue 6, June 2026.System identification and particle image velocimetry reveal how a modular robotic fish changes thrust physics across gaits. A traveling‐wave, fish‐like motion draws thrust from resistive drag, while a resonant standing‐wave motion is driven by reactive pressure.

Dye visualization of the wake of a near-wall particle in response to a periodic oscillation
Measurement: Sensors, 2021 In turbulent dispersed multiphase flows, the interaction between the particle wake and the ambient turbulent fluctuation can be crucial for the change of the multiphase system.

Hydrodynamic and ecological effects of engineered logjams: Insights from field observations
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.Drone imaging, LSPIV and electrofishing data quantified restoration effects of engineered logjam at the Emme River (Switzerland). Placement and discharge shaped flow: Side jams created longer wakes, centre jams stronger mixing; and lower discharge intensified gap velocities, whereas wake length remained stable.
