A Review of the Homogenized Lattice Boltzmann Method for Particulate Flow Simulations: From Fundamentals to Applications

Powders
The homogenized lattice Boltzmann method (HLBM) has emerged as a flexible computational framework for studying particulate flows, providing a monolithic approach to modeling pure fluid flows and flows through porous media, including moving solid and ...

A Study on Shape-Dependent Settling of Single Particles with Equal Volume Using Surface Resolved Simulations

Computation, 2021
A detailed knowledge of the influence of a particle’s shape on its settling behavior is useful for the prediction and design of separation processes. Models in the available literature usually fit a given function to experimental data.

Homogenized lattice Boltzmann methods for fluid flow through porous media – Part I: Kinetic model derivation

ESAIM: Mathematical Modelling and Numerical Analysis, 2023
In this series of studies, we establish homogenized lattice Boltzmann methods (HLBM) for simulating fluid flow through porous media. Our contributions in part I are twofold. First, we assemble the targeted partial differential equation system by formally unifying the governing equations for non-stationary fluid flow in porous media.

Simulation of Particulate Matter Structure Detachment from Surfaces of Wall-Flow Filters for Elevated Velocities Applying Lattice Boltzmann Methods

Fluids, 2023
Rearrangement events in wall-flow filters lead to the formation of specific deposition patterns, which affect a filter’s pressure drop, its loading capacity and the separation efficiency.

Efficient fluid structure interaction simulation of vocal fold oscillations using a homogenized Lattice Boltzmann Method

Computer Methods in Applied Mechanics and Engineering
Computational modeling of human phonation is a uniquely challenging fluid–structure interaction (FSI) problem. It is constrained both by the large computational cost and numerical restrictions of existing methods, particularly in handling vocal fold (VF) contact.

Homogenized color-gradient lattice Boltzmann model for immiscible two-phase flow in multiscale porous media

Journal of Applied Physics
In this paper, a homogenized multiphase lattice Boltzmann (LB) model is established for parallelly simulating immiscible two-phase flow in both solid-free regions (pore scale) and porous areas (continuum scale).

Efficient wall-modelled large eddy simulation of rotors using homogenized lattice Boltzmann methods

International Journal of Numerical Methods for Heat & Fluid Flow
Purpose Accurately capturing the dynamic forces acting on rotors as well as their wake effects presents a significant challenge for computational fluid dynamics due to high Reynolds numbers and a large range of spatio-temporal scales.

Numerical Investigation of the Settling Behavior of Non-Spherical Particles - Application of Homogenized Lattice Boltzmann Methods

, 2021
Zur Verbesserung von Trennprozessen bezüglich der Effizienz und Selektivität ist es notwendig, das Wissen über das Verhalten von Partikeln in Strömungen zu erweitern. Dies ist insbesondere der Fall für Partikel im Größenbereich um $1\textrm{µm}$, da hier weder die Diffusion, noch Trägheitseffekte die Dynamik dominant bestimmen.
