Consistent Lattice Boltzmann Method [PDF]

open access: yesPhysical 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

Asymptotic analysis of multiple-relaxation-time lattice Boltzmann schemes for mixture modeling [PDF]

open access: yes, 2008
A new lattice Boltzmann model for simulating ideal mixtures has been developed by means of the multiple-relaxation-time (MRT) approach. When compared with the previous single-relaxation-time (SRT) formulation of the same model, based on the continuous ...

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.

Crystallographic Lattice Boltzmann Method [PDF]

open access: yesScientific 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 ...

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 ...

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.
