Immersed boundary methods (IBMs) are versatile and efficient computational techniques to
solve flow problems in complex geometric configurations that retain the simplicity and …

It is challenging to model granular particles with arbitrary shapes and related complications
to fluid–particle interactions for granular flows which are widely encountered in nature and …

Turbulent flows laden withlarge, deformable drops or bubbles are ubiquitous in nature and a
number of industrial processes. These flows are characterized by physics acting at many …

The gravity-driven motion of rigid particles in a viscous fluid is relevant in many natural and
industrial processes, yet this has mainly been investigated for spherical particles. We …

We present a collision model for phase-resolved Direct Numerical Simulations of sediment
transport that couple the fluid and particles by the Immersed Boundary Method. Typically, a …

We investigate the behavior of the pseudocritical temperature of N f= 2+ 1 QCD as a function
of a static magnetic background field for different values of the pion mass, going up to m π≃ …

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 present a direct comparison between interface-resolved and one-way-coupled point-
particle direct numerical simulations (DNS) of gravity-free turbulent channel flow laden with …

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 …

Drag force is essential to dense flows, but the accurate and robust drag model is still an
open issue. Direct numerical simulations of a shallow and a deep bubbling bed of moving …
