Anisotropic particles are common in many industrial and natural turbulent flows. When these
particles are small and neutrally buoyant, they follow Lagrangian trajectories while …

The dynamical behavior of tiny elongated particles in a directly simulated turbulent flow field
is investigated. The ellipsoidal particles are affected both by inertia and hydrodynamic forces …

This letter reports on the pronounced turbulence modulations and the accompanying drag
reduction observed in a two-way coupled simulation of particle-laden channel flow. The …

Direct numerical simulation (DNS) of small prolate ellipsoidal particles suspended in a
turbulent channel flow is reported. The coupling between the fluid and the particles is one …

In this study, the rotation of small rigid fibers relative to the surrounding fluid in wall-bounded
turbulence is examined by means of direct numerical simulations coupled with Lagrangian …

This work aims to introduce a groundbreaking approach by directly computing the Fokker–
Planck equation, providing a mesoscopic scale orientation indicator based on the 2D …

We use three-dimensional Voronoï analysis and results from a direct numerical simulation to
study the preferential concentration of inertial particles in a vertical channel flow at Reynolds …

The rotational behaviour of non-spherical particles in turbulent channel flow is studied by
Lagrangian tracking of spheroidal point particles in a directly simulated flow. The focus is on …

The rotational motion of inertia-free spheroids has been studied in a numerically simulated
turbulent channel flow. Although inertia-free spheroids were translated as tracers with the …

We present experiments on rigid, nylon fiber translation, orientation, and rotation dynamics
(one-way coupled) in a fully developed turbulent channel flow (Friction Reynolds number …
