摘要
In the present paper the low Mach number limit of kinetic equations is used to develop a discretization for the incompressible Navier-Stokes equation. The kinetic equation is discretized with a first- and second-order discretization in space. The discretized equation is then considered in the low Mach number limit. Using this limit a second-order discretization for the convective part in the incompressible Navier-Stokes equation is obtained. Numerical experiments are shown comparing different Approaches.
