Renormalization of the lattice Boltzmann hierarchy [PDF]

open access: yesPhysical Review E, 2007
Is it possible to solve Boltzmann-type kinetic equations using only a small number of particles velocities? We introduce a novel techniques of solving kinetic equations with (arbitrarily) large number of particle velocities using only a lattice Boltzmann method on standard, low-symmetry lattices.

Advection–Diffusion Lattice Boltzmann Method With and Without Dynamical Filter

open access: yesFrontiers in Physics, 2022
In multi-component flow and/or thermal flows, when the diffusion coefficient of the advection–diffusion equation is relatively small, the relaxation coefficient in the lattice Boltzmann method will be close to 0.5, which will lead to numerical ...

A lattice Boltzmann model for squirmers [PDF]

open access: yesThe Journal of Chemical Physics, 2019
The squirmer is a simple yet instructive model for microswimmers, which employs an effective slip velocity on the surface of a spherical swimmer to describe its self-propulsion. We solve the hydrodynamic flow problem with the lattice Boltzmann (LB) method, which is well-suited for time-dependent problems involving complex boundary conditions ...

An upwind lattice Boltzmann scheme

open access: yesCoRR, 2021
A lattice Boltzmann scheme that is close to pure upwind, low diffusive and entropy satisfying Engquist-Osher scheme has been formulated for hyperbolic scalar conservation laws. A model for source terms, with scalar conservation laws, is introduced to remove the numerical imbalance between convection and source terms.

A Multiple-Grid Lattice Boltzmann Method for Natural Convection under Low and High Prandtl Numbers

open access: yesFluids, 2021
A multi-distribution lattice Boltzmann Bhatnagar–Gross–Krook (BGK) model with a multiple-grid lattice Boltzmann (MGLB) model is proposed to efficiently simulate natural convection over a wide range of Prandtl numbers. In this method, different grid sizes
