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 ...

Parametric lattice Boltzmann method [PDF]
Journal 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.

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

Volumetric Lattice Boltzmann Models in General Curvilinear Coordinates: Theoretical Formulation
Frontiers 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 ...
