Generalization of the Grad Theory to Polyatomic Gases
Résumé
We generalize the Grad theory to polyatomic gases with a continuous internal energy. To this end, we consider the generalized Borgnakke-Larsen model, and also a model derived of a monoatomic gas in dimension higher than three. We give an explicit fourteen moments system, computed for a diatomic gas and a Hard Sphere potential. Finally, we show how it can be reduced to standard Navier-Stokes equations.
