Fully resolved simulation of single-particle dynamics in a microcavity

Microfluidics and Nanofluidics, 2018
Fluid flow laden with a single finite size neutrally buoyant particle over a confined microcavity adjacent to a main straight microchannel is numerically simulated by a fully resolved simulation method. This method is based on coupled immersed boundary–lattice Boltzmann method, which can directly resolve the fluid flow and the interactions between ...

Particle resolved simulations of carbon oxidation in a laminar flow

The Canadian Journal of Chemical Engineering, 2014
This work is devoted to the numerical study of the impact of the Reynolds number and the ambient gas temperature on the partial oxidation of a single moving coal particle. The model includes six gaseous chemical species, three semi‐global heterogeneous surface reactions, and three homogeneous gas reactions.

Fully Resolved Simulations of Stationary Particles in Turbulent Flow

Volume 1: Fora, Parts A, B, C, and D, 2003
Gas flows containing a dilute loading of solid particle constitute an important class of multiphase flows. In most cases the gas flow is turbulent, and the interactions between the particles and the turbulence offer major modeling challenges. Many numerical models implicitly assume that the particles are significantly smaller than all turbulence length

Particle-Resolved Simulations of Solid-Liquid Systems

2017
Solid-liquid flows span a large parameter space, with dimensionless coordinates such as Stokes numbers, the solids volume fraction, the density ratio between the phases, and Reynolds numbers (e.g. associated with the continuous phase flow). We are interested in systems with appreciable inertia effects—i.e.

Particle-resolved CFD simulations of catalytic flow reactors

2016
Mit der Trockenreformierung (DRM) kann Synthesegas aus bedingt abbauwürdigen Erdgasquellen und Kohlendioxid hergestellt werden. Beides sind Treibhausgase. Üblicherweise wird die DRM in Festbettreaktoren mit kleinem Rohr-zu-Partikeldurchmesserverhältnis realisiert.

Particle-resolved direct numerical simulation of particle-laden turbulent channel flow

Physics of Fluids
Particle-resolved direct numerical simulations for particle-laden turbulent channel flow are performed by lattice Boltzmann method coupled with discrete element method. The modulation effects of particles on turbulent flow and spatial particle dispersion are studied under wide particle-to-fluid density ratio (ρp/ρf) ranging from 1.5 to 10 and solid ...
