Macroscopic Lattice Boltzmann Method [PDF]

open access: yesWater, 2020
The lattice Boltzmann method (LBM) is a highly simplified model for fluid flows using a few limited fictitious particles. It has been developed into a very efficient and flexible alternative numerical method in computational physics, demonstrating its great power and potential for resolving more and more challenging physical problems in science and ...

Application of Regularized Lattice Boltzmann Method for Incompressible Flow Simulation at High Reynolds Number and Flow with Curved Boundary

open access: yesJournal of Fluid Science and Technology, 2011
Single-relaxation time lattice Boltzmann method lacks the required numerical stability for high Reynolds number flow simulations. The method is also restricted to Cartesian grid, making it difficult to be implemented in flow with curved boundary ...

Direct numerical simulation of complex viscoelastic flows via fast lattice-Boltzmann solution of the Fokker–Planck equation [PDF]

open access: yes, 2013
Micro–macro simulations of polymeric solutions rely on the coupling between macroscopic conservation equations for the fluid flow and stochastic differential equations for kinetic viscoelastic models at the microscopic scale.

A note on the lattice Boltzmann method beyond the Chapman Enskog limits [PDF]

open access: yes, 2005
A non-perturbative analysis of the Bhatnagar-Gross-Krook (BGK) model kinetic equation for finite values of the Knudsen number is presented. This analysis indicates why discrete kinetic versions of the BGK equation, and notably the Lattice Boltzmann ...

Simulations of time harmonic blood flow in the Mesenteric artery: comparing finite element and lattice Boltzmann methods

open access: yesBioMedical Engineering OnLine, 2009
Background Systolic blood flow has been simulated in the abdominal aorta and the superior mesenteric artery. The simulations were carried out using two different computational hemodynamic methods: the finite element method to solve the Navier Stokes ...

On triangular lattice Boltzmann schemes for scalar problems

open access: yes, 2013
We propose to extend the d'Humi\'eres version of the lattice Boltzmann scheme to triangular meshes. We use Bravais lattices or more general lattices with the property that the degree of each internal vertex is supposed to be constant.

Simulation of Cavity Flow by the Lattice Boltzmann Method

open access: yes, 1994
A detailed analysis is presented to demonstrate the capabilities of the lattice Boltzmann method. Thorough comparisons with other numerical solutions for the two-dimensional, driven cavity flow show that the lattice Boltzmann method gives accurate ...
