Génie des matériaux Equation d'étatÉquilibre thermodynamique Mie-Grüneisen Onde de choc Changement de phaseThe Mie-Grüneisen equation of state is defined in an incomplete form P (V , E) which does not allow access to temperature and entropy. We show here how we can extend it to a complete equation of state in the S(V , E) form by providing an additional independent function which defines the heat capacity variations and then gives access to all the thermodynamic properties.

A new method for the determination of the equilibrium composition of gaseous mixtures is described. This method is particularly suited for both manual or computer calculations and leads to fast convergence. The mathematical formulation is detailed and a numerical example shows the calculation procedure.
