Abstract The impact of flow on aquatic organisms (and vice versa) is crucial for many aspects of their physiology and ecology, as this interaction shapes the hydrodynamic boundary layer and thereby the exchange of solutes between the organism and its surrounding environment.

ABSTRACT Pressure pulsation is a key factor affecting the safe and stable operation of pump‐turbines. This article is based on same frequency‐tracking method on the pressure pulsation propagation characteristics of pump‐turbine during generation mode. The numerical simulation is validated by experimental study on a model pump‐turbine.

Nondiffracting supertoroidal pulses and optical “Kármán vortex streets”
Supertoroidal light pulses, as space-time nonseparable electromagnetic waves, exhibit unique topological properties including skyrmionic configurations, fractal-like singularities, and energy backflow in free space, which however do not survive upon ...

The vortex street as a statistical-mechanical phenomenon [PDF]
An explanation of the Karman vortex street is presented on the basis of the two-temperature canonical distribution for inviscid two-dimensional flows in Navier-Stokes fluids or guiding-center ...

Universal scaling law in drag-to-thrust wake transition of flapping foils
Reversed von K\'arm\'an streets are responsible for a velocity surplus in the wake of flapping foils, indicating the onset of thrust generation. However, the wake pattern cannot be predicted based solely on the flapping peak-to-peak amplitude $A$ and ...

Wonders of Harbor and Grey Seal Whiskers: Morphology, Natural Frequencies, and 3D Modeling
Seals detect prey by sensing vortices using whiskers. How whisker morphologies and locations respond to hydrodynamic signals across various frequencies remains unclear. This study measures whiskers’ natural frequencies and morphologies and maps them to whisker locations on the muzzle, providing insights into how seals interpret hydrodynamic signals ...
