This library is written in Modelica. The purpose of this library is to calculate fluid properties from an equation of state (EoS), directly within Modelica and not from an external dll. 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.

So far, the fluids n-Butane, R134a and Isobutane are implemented, but not fully validated. The next fluids to be implemented are probably isopentane, propane, ammonia, CO2 and other possible working fluids for Organic-Rankine-Cycles.
