Anisotropic particles in turbulence

GA Voth, A Soldati - Annual Review of Fluid Mechanics, 2017 - annualreviews.org
Anisotropic particles are common in many industrial and natural turbulent flows. When these
particles are small and neutrally buoyant, they follow Lagrangian trajectories while …

Experimental investigation of inertial fibres and disks in a turbulent boundary layer

LJ Baker, F Coletti - Journal of Fluid Mechanics, 2022 - cambridge.org
We study experimentally the behaviour of negatively buoyant disks and fibres in a turbulent
boundary layer. The regime is relevant to the transport of natural sediment or plastic …

Slip velocity of rigid fibers in turbulent channel flow

L Zhao, C Marchioli, HI Andersson - Physics of Fluids, 2014 - pubs.aip.org
In this study, the slip velocity between rigid fibers and a viscous carrier fluid is investigated

Dynamics of single, non-spherical ellipsoidal particles in a turbulent channel flow

DO Njobuenwu, M Fairweather - Chemical Engineering Science, 2015 - Elsevier
Using disk, spherical and needle-like particles with equal equivalent volume diameters, the
orientational dynamics of non-spherical particles is studied in a turbulent channel flow. An …

[HTML][HTML] The TU Wien Turbulent Water Channel: Flow control loop and three-dimensional reconstruction of anisotropic particle dynamics

V Giurgiu, GCA Caridi, M Alipour, M De Paoli… - Review of Scientific …, 2023 - pubs.aip.org
A horizontal water channel facility was built to study particle dynamics in a turbulent flow.
The channel is sufficiently long to produce fully developed turbulence at the test section, and …

Simulation of inertial fibre orientation in turbulent flow

DO Njobuenwu, M Fairweather - Physics of Fluids, 2016 - pubs.aip.org
The spatial and orientational behaviour of fibres within a suspension influences the
