An investigation into the aerodynamic characteristics of catenary contact wires in a cross-wind [PDF]

open access: yes, 2001
An experimental analysis of the aerodynamic characteristics of catenary contact wires is presented. The aerodynamic data obtained were used to calculate the Glauert-Den Harthog criterion for one-dimensional galloping.

The interaction between flow-induced vibration mechanisms of a square cylinder with varying angles of attack [PDF]

open access: yes, 2012
This study examines the influence of angle of attack of a square section cylinder on the cylinder’s flow-induced vibration, where the direction of the vibration is transverse to the oncoming flow.

Dynamical determinants enabling two different types of flight in cheetah gallop to enhance speed through spine movement

open access: yesScientific Reports, 2021
Cheetahs use a galloping gait in their fastest speed range. It has been reported that cheetahs achieve high-speed galloping by performing two types of flight through spine movement (gathered and extended).

The galloping of a 4:1 rectangular cylinder at Re = 300

open access: yesAIP Advances, 2023
The flow-induced vibration (FIV) of a rectangular cylinder with a side ratio of 4 at Re = 300 is numerically investigated by a two-dimensional spectral-element method. The cylinder is constrained to vibrate only in the cross-flow direction.

Transverse galloping of two-dimensional bodies having a rhombic cross-section [PDF]

open access: yes, 2014
Transverse galloping is a type of aeroelastic instability characterized by oscillations perpendicular to wind direction, large amplitude and low frequency, which appears in some elastic two-dimensional bluff bodies when they are subjected to an incident ...

Meta‐Virtuality: Strategies of Disembeddedness in Virtual Interiorities

open access: yesJournal of Interior Design, EarlyView., 2022
ABSTRACT To reclaim their seat in the rapidly growing market of virtual space, designers of the built environment can benefit from reevaluating theories that see the virtual as a mere extension/reflection of the physical. By claiming ontological autonomy from external worlds, the virtual is liberated from the hegemonic control of the physical.

Experimental Investigation of Flow-Induced Motion and Energy Conversion of a T-Section Prism

open access: yesEnergies, 2018
Flow-induced motion (FIM) performs well in energy conversion but has been barely investigated, particularly for prisms with sharp sections. Previous studies have proven that T-section prisms that undergo galloping branches with high amplitude are ...

Optimal electromagnetic energy extraction from transverse galloping [PDF]

open access: yes, 2014
A fully coupled electro-fluid-elastic model for electromagnetic energy harvesting from Transverse Galloping is presented here. The model considers a one degree-of-freedom galloping oscillator where fluid forces are described resorting to quasi-steady ...
