Journal ArticleDOI

Lattice BGK Models for Navier-Stokes Equation

TL;DR: In this article, the Navier-Stokes equation is obtained from the kinetic BGK equation at the second-order approximation with a properly chosen equilibrium distribution, with a relaxation parameter that influences the stability of the new scheme.
Journal ArticleDOI

Theory of the lattice boltzmann method: dispersion, dissipation, isotropy, galilean invariance, and stability

TL;DR: The generalized hydrodynamics (the wave vector dependence of the transport coefficients) of a generalized lattice Boltzmann equation (LBE) is studied in detail and linear analysis of the LBE evolution operator is equivalent to Chapman-Enskog analysis in the long-wavelength limit (wave vector k=0).
Journal ArticleDOI

Multiple-relaxation-time lattice Boltzmann models in three dimensions.

TL;DR: Simulation of a diagonally lid–driven cavity flow in three dimensions clearly demonstrate the superior numerical stability of the multiple–relaxation–time lattice Boltzmann equation over the popular lattice Bhatnagar–Gross–Krook equation.
Journal ArticleDOI

Momentum transfer of a Boltzmann-lattice fluid with boundaries

TL;DR: In this article, the velocity boundary condition for curved boundaries in the lattice Boltzmann equation (LBE) was studied for moving boundaries by combination of the "bounce-back" scheme and spatial interpolations of first or second order.
Journal Article

Lattice gas hydrodynamics in two and three dimensions

TL;DR: It is shown for a class of D-dimensional lattice gas models how the macrodynamical equations for the densities of microscopically conserved quantities can be systematically derived from the underlying exact ''microdynamical'' Boolean equations.
