Simulation of three-dimensional homogeneous isotropic turbulence using the moment-based lattice Boltzmann method and LES-lattice Boltzmann method

open access: yesJournal of Fluid Science and Technology, 2014
Three-dimensional homogeneous isotropic turbulence simulations are conducted using moment-based lattice Boltzmann method and the large-eddy simulation based lattice Boltzmann method. for two Taylor's microscale Reynolds number, Reλ = 225 and Reλ = 314. On comparing the results obtained from these two methods, we found that the two methods produced

Transport in quenched disorder: light diffusion in strongly heterogeneous turbid media [PDF]

open access: yes, 2013
We present a theoretical and experimental study of light transport in disordered media with strongly heterogeneous distribution of scatterers formed via non-scattering regions.

Fast computation of effective diffusivities using a semi-analytical solution of the homogenization boundary value problem for block locally-isotropic heterogeneous media

open access: yes, 2020
Direct numerical simulation of diffusion through heterogeneous media can be difficult due to the computational cost of resolving fine-scale heterogeneities.

Lattice-Boltzmann Method for Geophysical Plastic Flows

open access: yes, 2015
We explore possible applications of the Lattice-Boltzmann Method for the simulation of geophysical flows. This fluid solver, while successful in other fields, is still rarely used for geotechnical applications.

Coupled DEM-LBM method for the free-surface simulation of heterogeneous suspensions

open access: yes, 2014
The complexity of the interactions between the constituent granular and liquid phases of a suspension requires an adequate treatment of the constituents themselves.

Droplet dynamics in homogeneous isotropic turbulence with the immersed boundary–lattice Boltzmann method

open access: yesPhysical Review E
We develop a numerical method for simulating the dynamics of a droplet immersed in a generic time-dependent velocity gradient field. This approach is grounded on the hybrid coupling between the lattice Boltzmann (LB) method, employed for the flow simulation, and the immersed boundary (IB) method, utilized to couple the droplet with the surrounding ...

Large enhancement of the effective second-order nonlinearity in graphene metasurfaces [PDF]

open access: yes, 2019
Using a powerful homogenization technique, one- and two-dimensional graphene metasurfaces are homogenized both at the fundamental frequency (FF) and second harmonic (SH).

Hydrodynamic forces on steady and oscillating porous particles

open access: yes, 2012
We derive new analytical results for the hydrodynamic force exerted on a sinusoidally oscillating porous shell and a sphere of uniform density in the Stokes limit. The coupling between the spherical particle and the solvent is done using the Debye-Bueche-

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

open access: yes, 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.
