Multiphase chemical reactors with characteristic multiscale structures are intrinsically
discrete at the elemental scale. However, due to the lack of multiscale models and the …

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 …

We study numerically the inertial migration of a single rigid sphere and an oblate spheroid in
straight square and rectangular ducts. A highly accurate interface-resolved numerical …

The paper reports on three direct numerical simulations of sediment transport with different
prototypical non-spherical particle shapes, ranging from prolate to oblate to a triaxial …

Sediment transport simulations face the challenge of accounting for vastly different scales in
space and time that cannot be tackled by a unifying approach. Instead, processes are …

Controlling heat and mass transfer in particulate suspensions has many applications in fuel
combustion, food industry, pollution control and life science. We perform direct numerical …

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 …
