High order boundary conditions for Lattice Boltzmann Schemes

M.M. Tekitek, F. Dubois and P. Lallemand

Abstract
Our communication will be divided into two parts. In the first part, we show that it is possible to get the macroscopic fluid equations of lattice Boltzmann schemes with an external force using Taylor expansion. In a second part of our contribution, we validate this general expansion by a detailed application to boundary conditions.
