Detailed Description

General class for Equation of State (EOS).

This is a pure virtual class: can not be instantiated.

This base class and its derived classes contain mainly computational functions to obtain thermodynamical values for each phase: pressure, temperature, internal energy...

In this ECOGEN release these are the EOS available:

ideal Gas (sub class EosIG), Stiffened (sub class EoSG), Noble-Abel Stiffened Gas (sub class EosNASG), Van der Waals (sub class EosVDW), polynomial (sub class EosPolynomial).

Appropriate data for EOS leads to a large choice of gas, liquid or compressible solid.
