Modelica library for the calculation of fluid properties from an equation of state (EoS).
This library calculates fluid properties from an equation of state (EoS) directly within Modelica. It supports EoS of the form f=f(T,d) meaning Helmholtz energy as a funtion of temperature and density. In addition to all state properties, this library calculates viscosity, thermal conductivity and surface tension.
A general description of the library can be found in the related publications:
