The Lagrangian View-Point Compared with the Eulerian One, in the Framework of Extended Thermodynamics

Abstract

The salient points of Extended Thermodynamics are here revised according to the Lagrangian view-point. The conservation laws of mass, momentum and energy, from the Lagrangian view-point, have already been treated in literature. Here a similar procedure is followed for all the balance laws of Extended Thermodynamics with an arbitrary number of moments. It is also shown how the Galilean Relativity Principle and some symmetry condition, which are present in the Eulerian view-point, can be "translated" in the Lagrangian view-point, where they are no more so self-evident.
