Matrix lattice Boltzmann reloaded [PDF]

open access: yes, 2011
The lattice Boltzmann equation has been introduced about twenty years ago as a new paradigm for computational fluid dynamics. In this paper, we revisit the main formulation of the lattice Boltzmann collision integral (matrix model) and introduce a new ...

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.

Lattice Boltzmann method for consolidation analysis of saturated clay

open access: yesJournal of Ocean Engineering and Science, 2019
The lattice Boltzmann method (LBM) has been widely employed in various areas of practical engineering to solve non-linear problems, due to such advantages as the simplicity of programming and the numerical efficiency.

General Propagation Lattice Boltzmann Model for the Boussinesq Equation

open access: yesEntropy, 2022
A general propagation lattice Boltzmann model is used to solve Boussinesq equations. Different local equilibrium distribution functions are selected, and the macroscopic equation is recovered with second order accuracy by means of the Chapman–Enskog ...

Generalized Boltzmann equation for lattice gas automata [PDF]

open access: yesJournal of Statistical Physics, 1995
In this paper, for the first time a theory is formulated that predicts velocity and spatial correlations between occupation numbers that occur in lattice gas automata violating semi-detailed balance. Starting from a coupled BBGKY hierarchy for the $n$-particle distribution functions, cluster expansion techniques are used to derive approximate kinetic ...

A thermal lattice Boltzmann model for micro/nano-flows [PDF]

open access: yes, 2008
The dynamic behavior of charged micro and nanofluids plays a crucial role in a large variety of industrial and biological processes. Such dynamic behavior is characterized by the simultaneous occurrence of several competing mechanisms, such as ...
