Reference Models

Reference models are thermodynamic models that are designed to represent the behavior of a specific fluid or a class of fluids. These models are used to calculate the thermodynamic properties of the fluid, such as enthalpy, entropy, and specific heat capacity, as a function of temperature and pressure.

The main purpose of the reference models is to be able to compute thermodynamic properties of a pure fluid with high accuracy and reliability, and are generally not suitable for mixture calculations. Typically, they are developed as Helmholtz energy explicit equations of state, but other types of models can also be used.

XLThermo relies on the CoolProp calculation engine to compute thermodynamic properties using reference models. Proceed to the next page to see what reference models are available in XLThermo.
