Numerical analysis of vortex shedding [PDF]

open access: yes, 2010
This report deals with structural vibrations of wind exposed structures caused by the vortex shedding phenomena. The theory of vortex shedding and the field of study called aeroelastisity are presented. A case study of a light mast structure has been used as a study of the vortex shedding phenomena.

The onset of unsteadiness of two-dimensional bodies falling or rising freely in a viscous fluid: a linear study [PDF]

open access: yes, 2012
We consider the transition between the steady vertical path and the oscillatory path of two-dimensional bodies moving under the effect of buoyancy in a viscous fluid.

Research on the Unsteady Flow and Vortex Characteristics of Cavitation at the Tongue in Centrifugal Pump [PDF]

open access: yesJournal of Applied Fluid Mechanics
In order to study the unsteady flow and vortex characteristics of tongue cavitation, numerical calculation is carried out for the whole flow channel given different conditions. Then, the calculation results are verified experimentally.

Effects of swirl numbers on the unsteady characteristics of pilot flame in a triple-swirler staged combustor

open access: yesCase Studies in Thermal Engineering, 2023
This paper studies the effects of the inner and outer pilot swirlers on the flame structures and thermo-acoustic instabilities in the triple-swirler staged combustors under various inner and outer pilot swirl numbers.

Dynamics of vortex shedding from slender cones [PDF]

open access: yes, 2009
PhDThe dynamics of vortex shedding from bluff bodies has been investigated experimentally for many decades, with the simple geometric case for the investigation being a uniform circular cylinder aligned with its axis normal to the flow. Even though

YIPFα1A expression is regulated by multilayered molecular mechanisms

open access: yesFEBS Open Bio, EarlyView.
YIPFα1A, a five‐pass Golgi protein, is regulated at multiple layers. (1) Rare‐codon enrichment drives translation‐coupled mRNA decay. (2) A proximal 3′‐UTR element stabilizes mRNA. (3) A distal 3′‐UTR element included by alternate poly(A) site usage represses translation, which can be overridden by the proximal 3′‐UTR element.

Investigation on mechanism of flow induced vibration of spiral tube bundle in cross lead bismuth flow

open access: yesHe jishu, 2021
BackgroundThe flow induced vibration of spiral tube bundle widely exists engineering practice. The traditional fluid medium is water and air, whilst lead bismuth fluid has gradually become a new heat exchange medium in recent years.PurposeThis study aims

Control of Polarization and Polar Helicity in BiFeO3 by Epitaxial Strain and Interfacial Chemistry

open access: yesAdvanced Functional Materials, EarlyView.
In BiFeO3 thin films, the interplay of interfacial chemistry, electrostatics, and epitaxial strain is engineered to stabilize homohelicity in polarization textures at the domain scale. The synergistic use of a Bi2O2‐terminated Aurivillius buffer layer and a highly anisotropic compressive epitaxial strain offers new routes to control the polar‐texture ...

Chemical Maturation Controls Bioavailability of Fetuin‐A‐Mineral Complexes in Biomineralization

open access: yesAdvanced Functional Materials, EarlyView.
The role of Fetuin‐A‐mineral complexes in matrix mineralization is unclear. Here, Fetuin‐A‐mineral complexes were found to exist in functionally distinct states that determine mineral bioavailability: chemically labile calciprotein monomers directly mineralize collagen fibrils, while chemically matured primary calciprotein particles require cellular ...

Investigation of Vortex-Induced Vibration of Double-Deck Truss Girder with Aerodynamic Mitigation Measures

open access: yesJournal of Marine Science and Engineering, 2023
The long-span double-deck truss girder bridge has become a recommend structural form because of its good performance on traffic capacity. However, the vortex-induced vibration (VIV) characteristics for double-deck truss girders are more complicated and ...
