Mechanism of heat transportation in the intermediate wake of a heated cylinder

Nihon Kikai Gakkai ronbunshu, 2020
The paper clarifies the effects of buoyancy on the mechanism of heat transfer in the wake of heated cylinder for X/D=5-40. Measurements are made by a thermo-anemometer.

Transition in vortex wakes of flow around an elliptic cylinder

Archives of Mechanics
Transition 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 ...

System Identification of Robotic Fish Swimming Reveals Roles of Reactive and Resistive Fluid Force in Two Distinct Swimming Gaits

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.

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.

Eco‐Evo‐Hydraulics: Integrating Fish Evolution Into Ecohydraulics for Conservation

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Riverine fish conservation in eco‐hydraulics is often based on restoring or regulating river habitat to a semi‐natural state. For example, ecohydraulic projects support fish populations by increasing river connectivity through fishways, and by maintaining or restoring natural flow variance to enhance habitat quality and availability.

Proper orthogonal decomposition analysis of vortex shedding behind a rotating circular cylinder

EPJ Web of Conferences, 2016
Turbulence studies were made in the wake of a rotating circular cylinder in a uniform free stream with the objective of describing the patterns of the vortex shedding up to suppression of the periodic vortex street at high velocity ratios, λ. The results

Bio‐to‐Robot Transfer of Fish Sensorimotor Dynamics via Interpretable Model

Advanced Intelligent Systems, Volume 8, Issue 3, March 2026.
This study demonstrates how a biologically interpretable model trained on real‐fish muscle activity can accurately predict the motion of a robotic fish. By linking real‐fish sensorimotor dynamics with robotic fish, the work offers a transparent, data‐efficient framework for transferring biological intelligence to bioinspired robotic systems.

VISUALIZATION OF THE KARMAN VORTEX STREET DUE TO NATURAL CONVECTION

JOURNAL OF THE FLOW VISUALIZATION SOCIETY OF JAPAN, 1988
The development of the Karman vortex street due to natural convection in the opposing flow was discovered and has been clarified by means of the numerical simulation by Noto & Matsumoto. A flow visualization is carried out to verify the numerical prediction on the development of the Karman vortex street.
