English abstract:
A small Knuden number analysis of a kinetic equation in the diffusive
scaling is performed. The collision kernel is of BGK type with a general
local Gibbs state.
Assuming that the flow velocity is of the order of the Knudsen number,
a Hilbert expansion yields a macroscopic model with finite temperature
variations, whose complexity lies in between
the hydrodynamic and the energy-transport equations.
Its mathematical structure is explored and macroscopic models for
specific examples of the global Gibbs state are presented.
