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 ...

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.

A pressure-based regularized lattice-Boltzmann method for the simulation of compressible flows

open access: yesThe Physics of Fluids, 2020
A new pressure-based lattice-Boltzmann method (HRR-p) is proposed for the simulation of flows for Mach numbers ranging from 0 to 1.5. Compatible with nearest-neighbor lattices (e.g., D3Q19), the model consists of a predictor step comparable to classical ...
