Detailed Description

A species thermodynamic property manager for a phase.

This is a general manager that can handle a wide variety of species thermodynamic polynomials for individual species and compute their nondimensional, reference-state thermodynamic properties (i.e. as a function of temperature only).

The ThermoPhase object relies on MultiSpeciesThermo to calculate the thermodynamic properties of the reference state for all of the species in the phase, for a range of temperatures. Note, the pressure dependence of the species thermodynamic functions is not handled at this level. Species using the same parameterization are grouped together in order to minimize the operation count and achieve better efficiency.

The most important member function for the MultiSpeciesThermo class is the member function MultiSpeciesThermo::update(). The function calculates the values of Cp/R, H/RT, and S/R for all of the species at once at the specified temperature.

Usually, all of the species in a phase are installed into a MultiSpeciesThermo object. However, there is no requirement that a MultiSpeciesThermo object handles all of the species in a phase. The member function install_STIT() is called to install each species into the MultiSpeciesThermo object.
