Advection–Diffusion Lattice Boltzmann Method With and Without Dynamical Filter
Frontiers 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 ...

Consistent Lattice Boltzmann Method [PDF]
Physical Review Letters, 2005 The problem of energy conservation in the lattice Boltzmann method is solved. A novel model with energy conservation is derived from Boltzmann's kinetic theory. It is demonstrated that the full thermo-hydrodynamics pertinent to the Boltzmann equation is recovered in the domain where variations around the reference temperature are small. Simulation of a

Crystallographic Lattice Boltzmann Method [PDF]
Scientific Reports, 2016 AbstractCurrent approaches to Direct Numerical Simulation (DNS) are computationally quite expensive for most realistic scientific and engineering applications of Fluid Dynamics such as automobiles or atmospheric flows. The Lattice Boltzmann Method (LBM), with its simplified kinetic descriptions, has emerged as an important tool for simulating ...

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

Hybrid Lattice Boltzmann Model for Nonlinear Diffusion and Image Denoising
Mathematics, 2023 In the present paper, a novel approach for image denoising based on the numerical solution to the nonlinear diffusion equation is proposed. The Perona–Malik-type equation is solved by employing a hybrid lattice Boltzmann model with five discrete ...

Initial and Boundary Conditions for the Lattice Boltzmann Method [PDF]
, 1993 A new approach of implementing initial and boundary conditions for the lattice Boltzmann method is presented. The new approach is based on an extended collision operator that uses the gradients of the fluid velocity.
