Abstract

We investigate discrete kinetic models in the fluid dynamic limit described by the Euler system and the Navier-Stokes correction obtained by the Chapman-Enskog procedure. We show why reliable ''small'' systems can be expected only for small Mach numbers and derive a calculus for designing models for given Prandtl numbers.
