This paper compares in detail the lattice Boltzmann method and an isothermal Navier-Stokes method. It is found that these two methods are closely related to each other. Both methods satisfy similar macroscopic governing equations in their continuous forms, but they differ from each other in their di

β¦ Synopsis
Combining an asymptotic analysis of the lattice Boltzmann method [M. Junk, Z. Yang, Asymptotic analysis of lattice Boltzmann boundary conditions, J. Stat. Phys. 121 (2005) 3-35] with the stability estimate presented in [M. Junk, W.-A. Yong, Weighted L 2 stability of the lattice Boltzmann equation, Preprint], we are able to prove some strict convergence results. The proof applies to the lattice Boltzmann method with linear collision operator both in the case of periodic domains and bounded domains if the Dirichlet boundary condition is realized with the bounce back rule.

## Abstract A numerical method was developed for flows involving an interface between a homogenous fluid and a porous medium. The numerical method is based on the lattice Boltzmann method for incompressible flow. A generalized model, which includes Brinkman term, Forcheimmer term and nonlinear conv
