The aim of this article is to construct a BGK-type model for polyatomic gases
which gives in the hydrodynamic limit the proper transport coefficient. Its
construction relies upon a systematic procedure: minimizing Boltzmann entropy
under suitable moments constraints (Levermore in J Stat Phys 83:1021–1065, 1996;
Brull and Schneider in Cont Mech Thermodyn 20(2):63–74, 2008). The obtained
model corre... hiện toàn bộ
