High Accuracy Volume Flow Rate Measurement Using Vortex Counting [PDF]

open access: yes, 2013
A prototype device for measuring the volumetric flow-rate by counting vortices has been designed and realized. It consists of a square-section pipe in which are placed a two-dimensional bluff body and a strain gauge force sensor.

Vibration of Bundled Conductors Following Ice Shedding [PDF]

open access: yes, 2008
The dynamic behavior of bundled conductors following ice shedding from one subconductor is examined numerically using the finite-element method. An existing model of ice shedding from a single conductor is improved by developing a model of spacers which ...

Aeolian tone radiated from a circular cylinder with solid spiral fin in cross flow

open access: yesJournal of Fluid Science and Technology, 2014
This study focuses on the characteristics of the Aeolian tone and Karman vortex shedding from a circular cylinder with a solid spiral fin. The fin pitch ratios range from 0.11 to 0.80.

Flow visualization observation of the interference vortex flow from a pair of square cylinders

open access: yesJournal of Fluid Science and Technology, 2023
In order to investigate the aspect of the mutual interference flow from two square cylinders, the visual water-flow observation experiment was performed. In the experiment, the pitch ratio L/d and the arrangement angle α were made into the parameter, and

Control of vortex shedding at moderate Reynolds numbers [PDF]

open access: yes, 2002
The suppression method of vortex shedding from a circular cylinder has been studied experimentally in the Reynolds number range from 300 to 1600. The test is performed in a water channel. The model cylinder is 1 cm in diameter and 38 cm in length.

Insights into Vortex Shedding with Data Analysis

open access: yesJournal of Fluid Science and Technology, 2009
Unsteady, three-dimensional characteristics of vortex shedding were studied with self-made MEMS sensors situated spanwisely on a circular cylinder subjected to uniform incoming flow. Firstly, verification on the reliability of the MEMS sensor signals was

Long Time Scale Fluctuation in the Irregularity of Vortex Shedding (Different Vortex Shedding Frequencies Detected at the Same Time in the Spanwise Direction of Wake behaind a Two-Dimensional Circular Cylinder) [PDF]

open access: yes, 2002
It is known that the long time scale fluctuation about 20 times the vortex shedding periodicity exists in the irregularity of the vortex shedding from a two-dimensional circular cylinder. However it's origination is not known yet.

Effects of Damping and Reynolds Number on Vortex-Induced Vibrations [PDF]

open access: yes, 2007
Vortex-induced vibrations have been studied experimentally with emphasis on damping and Reynolds number effects. Our system was an elastically-mounted rigid circular cylinder, free to oscillate only transverse to the flow direction, with very low ...

The essence of generating vortex-within-a-vortex structures behind forked caudal fins

open access: yesAIP Advances, 2022
This work focuses on vortex-within-a-vortex (VV) structures behind three different shapes of forked caudal fin with a heaving-pitching motion. The results show that the synchronization of trailing-edge vortex separation and the shedding of the leading ...
