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