Research on swimming hydrodynamics based on a three‐dimensional high‐precision fish model
River, Volume 4, Issue 3, Page 341-350, August 2025.Abstract Fish swimming hydrodynamics serves as a critical foundation for aquatic ecological conservation, with recent research extending from 2D to 3D perspectives. This study employs 3D high‐fidelity modeling with dynamic mesh technology to investigate how cylindrical obstacles at varying positions affect Carassius auratus locomotion. Analysis of nine

Some Current Advances in Cavitation Research [PDF]
, 1997 Several recent experimental and analytical investigations of cavitating flows have revealed new phenomena which clearly affect how we should view cavitation growth and collapse and the strategies used to ameliorate its adverse effects. On the scale of

Journal of Fish Biology, Volume 107, Issue 1, Page 52-62, July 2025.Abstract The deep‐sea demersal fish fauna is characterized by a prevalence of elongated‐body forms with long tapering tails. Using baited camera landers at depths of 4500–6300 m in the Pacific Ocean, we observed multiple instances of backward swimming using reverse undulation of the slender body in four species: the cutthroat eel Ilyophis robinsae ...

Lacustrine and fan‐delta sediments in syn‐rift lake basins
The Depositional Record, Volume 11, Issue 3, Page 857-892, June 2025.A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...

Surge Instability on a Cavitating Propeller [PDF]
, 2000 This study details experiments investigating a previously unrecognized surge instability on a cavitating propeller in a water tunnel. The surge instability is explored through visual observation of the cavitation on the propeller blades and in the tip ...

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 5, May 2025.Abstract Reservoir construction can alter the transport and export of nutrients and organic matter by rivers to coastal areas. However, influences from construction within the first years after flooding are not well understood. Here we present a 9‐year study of La Romaine Hydroelectric Complex, composed of four cascading boreal reservoirs sequentially ...

Observations of Oscillating Cavitation on a Flat Plate Hydrofoil [PDF]
, 2001 An experimental investigation was made to clarify the characteristics of oscillating cavitation on a flat plate hydrofoil in a water tunnel. Dynamic the behavior of oscillating cavitation is discussed from the unsteady pressure measurements at the ...
