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

Hybrid Lattice Boltzmann Model for Nonlinear Diffusion and Image Denoising

open access: yesMathematics, 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 ...

Fluctuating lattice Boltzmann [PDF]

open access: yesEurophysics Letters (EPL), 2005
The lattice Boltzmann algorithm efficiently simulates the Navier Stokes equation of isothermal fluid flow, but ignores thermal fluctuations of the fluid, important in mesoscopic flows. We show how to adapt the algorithm to include noise, satisfying a fluctuation-dissipation theorem (FDT) directly at lattice level: this gives correct fluctuations for ...

Volumetric Lattice Boltzmann Models in General Curvilinear Coordinates: Theoretical Formulation

open access: yesFrontiers in Applied Mathematics and Statistics, 2021
A theoretical formulation of lattice Boltzmann models on a general curvilinear coordinate system is presented. It is based on a volumetric representation so that mass and momentum are exactly conserved as in the conventional lattice Boltzmann on a ...

Parametric lattice Boltzmann method [PDF]

open access: yesJournal of Computational Physics, 2017
The discretized equilibrium distributions of the lattice Boltzmann method are presented by using the coefficients of the Lagrange interpolating polynomials that pass through the points related to discrete velocities and using moments of the Maxwell-Boltzmann distribution.
