Toward a fluid mechanics of suspensions

JF Morris - Physical Review Fluids, 2020 - APS
Suspensions are considered from the perspective of development of their bulk fluid
mechanics. Suspension mechanics has had a fluid mechanical basis since its inception, as …

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 …

Particle–fluid–wall interaction of inertial spherical particles in a turbulent boundary layer

LJ Baker, F Coletti - Journal of Fluid Mechanics, 2021 - cambridge.org
We study the dynamics of dilute, slightly negatively buoyant, millimetre-size spherical
particles fully suspended in a smooth-wall open channel flow. The Reynolds number is …

Scale-to-scale turbulence modification by small settling particles

R Hassaini, F Coletti - Journal of Fluid Mechanics, 2022 - cambridge.org
Despite decades of investigations, there is still no consensus on whether inertial particles
augment or dampen turbulence. Here, we perform the first experimental study in which the …

Effects of the finite particle size in turbulent wall-bounded flows of dense suspensions

P Costa, F Picano, L Brandt… - Journal of fluid …, 2018 - cambridge.org
We use interface-resolved numerical simulations to study finite-size effects in turbulent
channel flow of neutrally buoyant spheres. Two cases with particle sizes differing by a factor …

Dynamics and scaling of particle streaks in high-Reynolds-number turbulent boundary layers

T Berk, F Coletti - Journal of Fluid Mechanics, 2023 - cambridge.org
Inertial particles in wall-bounded turbulence are known to form streaks, but experimental
evidence and predictive understanding of this phenomenon is lacking, especially in regimes …

Particle resolved simulation of sediment transport by a hybrid parallel approach
