This paper presents a new immersed boundary method for rigid particles of arbitrary shape
and arbitrary density, which can be exactly zero. Especially in the latter case, the coupling of …

Direct numerical simulation of the gravity-induced settling of finite-size particles in triply
periodic domains has been performed under dilute conditions. For a single solid-to-fluid …

A Cartesian cut-cell method for viscous flows interacting with freely moving boundaries is
presented. The method enables a sharp resolution of the embedded boundaries and strictly …

We present results of direct numerical simulation of incompressible fluid flow over a thick
bed of mobile spherically shaped particles. The algorithm is based upon the immersed …

In this work we consider the pairwise interaction extended point-particle (PIEP) model for
Euler–Lagrange simulations of particle-laden flows. By accounting for the precise location of …

A numerical method based upon the immersed boundary technique for the fluid–solid
coupling and on a soft-sphere approach for solid–solid contact is used to perform direct …

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 …

The direct numerical simulation of particulate systems offers a unique approach to study the
dynamics of fluid-solid suspensions by fully resolving the submerged particles and without …

We present an immersed boundary/multi-relaxation time lattice Boltzmann method for the
particle-resolved simulation of particle-laden flows. The no-slip boundary condition is …

We have performed interface-resolved direct numerical simulations of forced homogeneous-
isotropic turbulence in a dilute suspension of spherical particles in the Reynolds number …
