Particle-laden turbulence: progress and perspectives

L Brandt, F Coletti - Annual Review of Fluid Mechanics, 2022 - annualreviews.org
This review is motivated by the fast progress in our understanding of the physics of particle-
laden turbulence in the last decade, partly due to the tremendous advances of measurement …

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 …

Turbulent channel flow of dense suspensions of neutrally buoyant spheres

F Picano, WP Breugem, L Brandt - Journal of Fluid Mechanics, 2015 - cambridge.org

Modulation of turbulence intensity by heavy finite-size particles in upward channel flow

Z Yu, Y Xia, Y Guo, J Lin - Journal of Fluid Mechanics, 2021 - cambridge.org
It has been recognized that, generally, large particles enhance the turbulence intensity,
while small particles attenuate the turbulence intensity. However, there has been no …

Rotation of nonspherical particles in turbulent channel flow

L Zhao, NR Challabotla, HI Andersson, EA Variano - Physical review letters, 2015 - APS
The effects of particle inertia, particle shape, and fluid shear on particle rotation are
examined using direct numerical simulation of turbulent channel flow. Particles at the …

Numerical study on the internal flow characteristics of an axial-flow pump under stall conditions

K Kan, Y Zheng, Y Chen, Z Xie, G Yang… - Journal of Mechanical …, 2018 - Springer
When an axial-flow pump works in low flow rate conditions, rotating stall phenomena will
probably occur, and the pump will enter hydraulic unsteady conditions. The rotating stall can …

[HTML][HTML] Shape-dependence of particle rotation in isotropic turbulence

M Byron, J Einarsson, K Gustavsson, G Voth… - Physics of …, 2015 - pubs.aip.org
We consider the rotation of neutrally buoyant axisymmetric particles suspended in isotropic
turbulence. Using laboratory experiments as well as numerical and analytical calculations …

Refractive-index-matched hydrogel materials for measuring flow-structure interactions

ML Byron, EA Variano - Experiments in fluids, 2013 - Springer
In imaging-based studies of flow around solid objects, it is useful to have materials that are
refractive-index-matched to the surrounding fluid. However, materials currently in use are …
