Simulating Anomalous Dispersion in Porous Media Using the Unstructured Lattice Boltzmann Method

Frontiers in Physics, 2015
Flow in porous media is a significant challenge to many computational fluid dynamics methods because of the complex boundaries separating pore fluid and host medium.

Does the multiresolution lattice Boltzmann method allow to deal with waves passing through mesh jumps?

Comptes Rendus. Mathématique, 2022
We consider an adaptive multiresolution-based lattice Boltzmann scheme, which we have recently introduced and studied from the perspective of the error control and the theory of the equivalent equations.

Lattice Boltzmann Magnetohydrodynamics

, 1994
Lattice gas and lattice Boltzmann methods are recently developed numerical schemes for simulating a variety of physical systems. In this paper a new lattice Boltzmann model for modeling two-dimensional incompressible magnetohydrodynamics (MHD) is ...

Quantum Lattice Boltzmann is a quantum walk [PDF]

, 2015
Numerical methods for the 1-D Dirac equation based on operator splitting and on the quantum lattice Boltzmann (QLB) schemes are reviewed. It is shown that these discretizations fall within the class of quantum walks, i.e. discrete maps for complex fields,

Solar Heating Enhanced Selective Recovery of Metal Ions Through Flowing Electrodes Enabled by Hybrid Carbon Nanostructures

Advanced Functional Materials, EarlyView.
A new electrochemical system based on a microporous hybrid of carbon nanoplatelets and nanotubes to selectively capture Ni2+ from wastewater is constructed. The system temperature rises rapidly when irradiated with sunlight, which enhances the Ni2+ removal rate by 250% and the selectivity by 53%, and the energy consumption is also reduced by 51 ...

Application of lattice Boltzmann method to solution of viscous incompressible fluid dynamics problems

Научно-технический вестник информационных технологий, механики и оптики
The possibilities of simulation of viscous incompressible fluid flows with lattice Boltzmann method are considered. Unlike the traditional discretization approach based on the use of Navier–Stokes equations, the lattice Boltzmann method uses a mesoscopic

Lattice Boltzmann methods applied to large‐scale three‐dimensional virtual cores constructed from digital optical borehole images of the karst carbonate Biscayne aquifer in southeastern Florida

Water Resources Research, 2014
Digital optical borehole images at approximately 2 mm vertical resolution and borehole caliper data were used to create three‐dimensional renderings of the distribution of (1) matrix porosity and (2) vuggy megaporosity for the karst carbonate Biscayne ...

Exactly Solvable Lattice Models with Crossing Symmetry [PDF]

, 2012
We show how to compute the exact partition function for lattice statistical-mechanical models whose Boltzmann weights obey a special "crossing" symmetry.
