Volume 9 ~ Issue 1

I analize here a 16 moments model for polyatomic gases because this is suggested by the limit, for light speed going to infinity, of the corresponding relativistic model. The Galilean relativity principle is imposed by using a methodology which was introduced some years ago by Pennisi and Ruggeri in the framework of monoatomic gases. It is here proved that it can be applied also for the equations of polyatomic gases. Moreover, some integrals will be calculated which are useful to find the explicit closure of the balance equations.

The hyperbolicity requiremet of a recent 16 moments model for RelativisticPolyatomic Gases is here proved for every time direction ξα. This is important because asures that the wave propagation ve- locities are finite and not higher than that of light. In addition to important mathematical consequences, this property also shows that the model respects the principle of cause and effect.
