Rheinländer, Martin Kilian 2009 Caiazzo, Alfonso Publ. in: Computers & Mathematics with Applications 58 (2009), 5, pp. 883-897 2011-03-22T17:49:00Z Junk, Michael Comparison of analysis techniques for the lattice Boltzmann method Rheinländer, Martin Kilian Caiazzo, Alfonso deposit-license eng Junk, Michael We show that the Chapman Enskog expansion can be viewed as a special instance of a general expansion procedure which also encompasses other methods like the regular error expansion and multi-scale techniques and that any two expansions which properly describe the lattice Boltzmann solution necessarily coincide up to higher order terms. For a model problem, both the regular error expansion and the Chapman Enskog expansion are carried out. It turns out that the classical Chapman Enskog method leads to an unstable equation at super-Burnett order in a parameter regime for which the underlying lattice Boltzmann algorithm is stable. However, our approach naturally allows us to consider variants of the super-Burnett equation which do not suffer from instabilities. The article concludes with a detailed comparison of the Chapman Enskog and the regular error expansion. 2011-03-22T17:49:00Z
