substantial attention due to its relevance in both natural and engineering contexts. The focus …

On the linear global stability analysis of rigid-body motion fluid–structure-interaction problems

PS Negi, A Hanifi, DS Henningson - Journal of Fluid Mechanics, 2020 - cambridge.org
A rigorous derivation and validation for linear fluid–structure-interaction (FSI) equations for a
rigid-body motion problem is performed in an Eulerian framework. We show that the 'added …

The assembly of freely moving rigid fibres measures the flow velocity gradient tensor

M Cavaiola, S Olivieri, A Mazzino - Journal of Fluid Mechanics, 2020 - cambridge.org
The motion of an assembly of rigid fibres is investigated for different classes of closed
streamline flows, steady or time dependent, two-dimensional or three-dimensional. In our …

Turbulence-driven reverse lift on two-dimensional and three-dimensional structures

Y Jin, L Yan, H Qiu, LP Chamorro - Physical Review E, 2018 - APS
Using laboratory experiments and simplified theoretical arguments, we show that the level of
turbulence may reverse the direction of the mean lift on two-and three-dimensional …

Probing fluid torque with a hydrodynamical trap: Rotation of chiral particles levitating in a turbulent jet

T Barois, PD Huck, C Paleo, M Bourgoin, R Volk - Physics of Fluids, 2019 - pubs.aip.org
A vertical turbulent jet is used to trap chiral particles. The particles are maintained in
levitation and a stationary rotation regime is observed. The model particles used are …

Particles and fibers in fluid flows for environmental applications

M Cavaiola - 2022 - tesidottorato.depositolegale.it
The thesis is divided in two parts showing applications of active and passive models, in
which the Lagrangian tracking of rigid fibers and slender swimmers can be employed to …

Elastically-bounded flapping plates for flow-induced energy harvesting

S Olivieri - 2020 - tesidottorato.depositolegale.it
This work concerns a novel concept for energy harvesting (EH) from fluid flows, based on
the aeroelastic flutter of elastically-bounded plates immersed in laminar flow. The resulting …

M Cavaiola, S Olivieri, A Mazzino - arXiv preprint arXiv:1908.04072, 2019 - arxiv.org
The motion of an assembly of rigid fibers is investigated for different classes of closed
streamline flows, steady or time dependent, two dimensional or three dimensional. In our …

On the dynamics of rigid and flexible structures under complex flows

Y Jin - 2019 - ideals.illinois.edu
Fluid-structure interaction (FSI) is a ubiquitous phenomenon of high relevance in
engineering systems. During the past decades, substantial efforts have been placed on …

[引用][C] 후방에부착된필라멘트길이에따른구의낙하현상

최승호, 이민형, 김대겸 - 대한기계학회춘추학술대회, 2022 - dbpia.co.kr
유동장 내부에 있는 고정된 물체의 뒤쪽에 splitter plate 가 있는 경우, splitter plate 에 의해
후류가 변하여 물체가 받는 drag 가 감소하게 된다. 또한, 필라멘트 역시 plate 와 마찬가지로 …
