In multiphase particulate systems, the turbulence of the continuous phase (gas or liquid) is
modulated due to interactions between the continuous phase and the suspended particles …

It has been recognized that, generally, large particles enhance the turbulence intensity,
while small particles attenuate the turbulence intensity. However, there has been no …

Modulation of the carrier phase turbulence by finite-size solid particles is relevant to many
industrial and environmental applications. Here we report particle-resolved simulations of a …

The discrete unified gas-kinetic scheme (DUGKS) is a relatively new, finite-volume
formulation of the Boltzmann equation. It has several advantages over the lattice Boltzmann …

The effects of the particle collision model in a direct-forcing fictitious domain method on the
fluid and particle statistics of a fully developed turbulent channel flow laden with finite-size …

Understanding the two-way interactions between finite-size solid particles and a wall-
bounded turbulent flow is crucial in a variety of natural and engineering applications …

This paper presents the derivations of the exact relations between skin friction and other
important dynamical and kinematical quantities on a stationary curved surface in a viscous …

The interactions between finite-size spheroidal particles and upward turbulent flows in a
vertical channel are numerically simulated with a direct-forcing fictitious domain method at …

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 …

Finite-size particles modulate wall-bounded turbulence, leading, for the case of spherical
particles, to increased drag also owing to the formation of a particle wall layer. Here, we …
