Application of lattice Boltzmann method to solution of viscous incompressible fluid dynamics problems

Научно-технический вестник информационных технологий, механики и оптики
The possibilities of simulation of viscous incompressible fluid flows with lattice Boltzmann method are considered. Unlike the traditional discretization approach based on the use of Navier–Stokes equations, the lattice Boltzmann method uses a mesoscopic

Correlations and Renormalization in Lattice Gases

, 1994
A complete formulation is given of an exact kinetic theory for lattice gases. This kinetic theory makes possible the calculation of corrections to the usual Boltzmann / Chapman-Enskog analysis of lattice gases due to the buildup of correlations.

A new model for simulating colloidal dynamics

, 2003
We present a new hybrid lattice-Boltzmann and Langevin molecular dynamics scheme for simulating the dynamics of suspensions of spherical colloidal particles. The solvent is modeled on the level of the lattice-Boltzmann method while the molecular dynamics

Stability analysis of the vectorial Lattice-Boltzmann method [PDF]

ESAIM: Proceedings and Surveys
We perform a stability analysis of the Vectorial Lattice-Boltzmann Method (VLBM). The VLBM has been introduced in [1–3, 9, 18]. It is a variant of the LBM with extended stability features: it allows handling compressible flows with shock waves, while the

Energy-Efficient Implementation of the Lattice Boltzmann Method

Energies
Energy costs are now one of the leading criteria when procuring new computing hardware. Until recently, developers and users focused only on pure performance in terms of time-to-solution.

Effects of nanoparticles on melting process with phase-change using the lattice Boltzmann method

Results in Physics, 2017
In this work, the problem of nanoparticles dispersion effects on coupled heat transfer and solid-liquid phase change has been studied. The lattice Boltzmann method (LBM) enthalpy-based is employed.

Entropy-Assisted Computing of Low-Dissipative Systems

Entropy, 2015
Entropy feedback is reviewed and highlighted as the guiding principle to reach extremely low dissipation. This principle is illustrated through turbulent flow simulations using the entropic lattice Boltzmann scheme.
