Modelling of coupled cross-flow/in-line vortex-induced vibrations using double Duffing and van der Pol oscillators [PDF]

, 2012
Many studies have typically applied a linear structural spring–mass–damper oscillator and a van der Pol wake oscillator to model a one-dimensional cross-flow vortex-induced vibration (VIV).

Flow control behind a circular cylinder via a porous cylinder in deep water

EPJ Web of Conferences, 2013
In this present work, the effects of surrounding outer porous cylinder on vortex structure downstream of a circular inner cylinder are investigated experimentally in deep water flow. The porosity of outer cylinder were selected as β = 0.4, 0.5, 0.6, 0.65,

Nano‐Scale Characterization of Impurities Segregation in Solid Oxide Electrolysis Cells

Advanced Functional Materials, EarlyView.
Cathodic polarization induces impurity segregation in Ni, forming an amorphous Na─Al─Si─O amorphous phase at grain boundaries. Under ultralow oxygen partial pressure, multiple elements dissolve, migrate, and reoxidize within the metal. A patterned model system provides direct nanoscale evidence, clarifying the mechanism of polarization‐driven impurity ...

Shape Memory Microneedle to Prevent Risks of Reproductive Hormone Therapy by Switching Sustained to Burst Release Under a Single Transdermal Insertion

Advanced Functional Materials, EarlyView.
A shape‐memory microneedle system enables reproductive hormone therapy through a single transdermal insertion. The X‐shaped device sustains follicle‐stimulating hormone release for three days, and mild heating restores the O shape to trigger burst human chorionic gonadotropin release.

Flow around a circular cylinder set normal to a plane wake of an upstream circular cylinder

JOURNAL OF THE FLOW VISUALIZATION SOCIETY OF JAPAN, 1987
In order to clarify flow around a circular cylinder set normal to a plane wake of an upstream circular cylinder of the same diameter, a windtunnel experiment and an open water-channel experiment have been performed at Reynolds-numbers ( based on the diameter of the cylinder and the main velocity ) of 2.9×104 and 680, respectively. Surface-flow patterns

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

, 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 ...
