Abstract: Summary In the low Mach number limit of the Lattice Boltzmann type models one obtains the incompressible Navier-Stokes equation. This is achieved by asymptotic analysis. Moreover in the course of this analysis, the Lattice Boltzmann Model reduces to a relaxation system which can be discretized using relaxation schemes. We present two variants of the relaxation schemes characterized by local approximation of characteristic speeds and a multidimensional flux approximation. These are applied to relaxation systems. Their performance will be discussed with reference to test cases of isothermal incompressible flow.
