Modeling and direct numerical simulation of particle-laden flows have a tremendous variety
of applications in science and engineering across a vast spectrum of scales from pollution …

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 …

Efficient solution-adaptive simulations are conducted by a Cartesian cut-cell method to
analyse the flow field of prolate ellipsoids in uniform flow. The parameter space defined by …

Settling of non-spherical particles is poorly understood with previous studies having focused
mainly on spherical particles. Here, a series of particle-resolved direct numerical simulations …

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 …

Microbial cell separation and recycling have become the major major high-cost procedures
in commercial fermentation biotechnology, especially for the difficult-to-cultivate strains. In …

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 …

We study suspensions of oblate rigid particles in a viscous fluid for different values of the
particle volume fractions. Direct numerical simulations have been performed using a direct …

In this paper, a three‐dimensional numerical solver is developed for suspensions of rigid
and soft particles and droplets in viscoelastic and elastoviscoplastic (EVP) fluids. The …

The buoyancy-driven motion of two identical gas bubbles released in line in a liquid at rest is
examined with the help of highly resolved simulations, focusing on moderately inertial …
