An overview of a Lagrangian method for analysis of animal wake dynamics [PDF]

open access: yes, 2008
The fluid dynamic analysis of animal wakes is becoming increasingly popular in studies of animal swimming and flying, due in part to the development of quantitative flow visualization techniques such as digital particle imaging velocimetry (DPIV).

Three dimensional flutter analysis and wind-tunnel experiments of a rectangular sheet supported by a wire (Influence of eccentricity on the flutter characteristics and occurrence condition)

open access: yesNihon Kikai Gakkai ronbunshu, 2016
This paper deals with the flutter analysis of a rectangular sheet supported by a wire in axial flow. In the flutter analysis, Doublet-Point Method based on unsteady lifting surface theory is used to calculate the unsteady fluid force acting on the sheet ...

Turbulent flow interacting with flexible trawl net structure including simulation catch in flume tank

open access: yesScientific Reports, 2023
The interaction between fluid and the midwater trawl with stocked catches is extremely complex, but essential to improve the understanding of the drag force acting on the trawl, the behavior of the fishing structure during a trawling process, and to ...

Ultra-fast escape maneuver of an octopus-inspired robot [PDF]

open access: yes, 2014
We design and test an octopus-inspired flexible hull robot that demonstrates outstanding fast-starting performance. The robot is hyper-inflated with water, and then rapidly deflates to expel the fluid so as to power the escape maneuver.

Dynamic Behaviour of a Flexible Yacht Sail Plan [PDF]

open access: yes, 2013
• Dynamic fluid structure interaction of a sail plan is modeled in harmonic pitching • Aerodynamic forces oscillations show hysteresis phenomena • Neglecting the structural deformation underestimates the forces oscillations • Both aerodynamic and ...

Simulation on Unsteady Crosswind Forces of a Moving Train in a Three-Dimensional Stochastic Wind Field

open access: yesApplied Sciences, 2022
Unsteady aerodynamic forces are significantly critical to the safety and stability of trains traveling in high winds. This paper describes a study into unsteady crosswind forces of a moving train subjected to a three-dimensional stochastic wind field ...

On the validation and use of high-fidelity numerical simulations for gust response analysis [PDF]

open access: yes, 2018
Specific gust response is considered as one of the most important loads encountered by an aircraft. The Certification Specification (CS) 25, defined by the European Aviation Safety Agency (EASA), and the Federal Aviation Regulations (FAR) 25, defined by ...

Mixed Convective MHD Micro-Polar Fluid Flow in a Porous Medium with Radiation Absorption [PDF]

open access: yesInternational Journal of Mathematical, Engineering and Management Sciences, 2019
An unsteady mixed convective flow of micro-polar fluid in a porous medium has been considered in presence of transverse magnetic field, Dufour effects and radiation. Effects of radiation absorption and heat source/sink are taken into account.
