Liquid enthalpy calculation methods

You can use the Liquid Enthalpy list in the Fluid Editor to change the liquid enthalpy calculation method for Compositional fluids. The Liquid Enthalpy list is available only for fluids that meet the following requirements:

• The fluid contains a liquid phase.

• The fluid uses the Ideal method or one of the equations of state as its system calculation method.

If you do not see the Liquid Enthalpy list in the Fluid Editor, the fluid uses its system calculation method to calculate the liquid enthalpy.

When you change the liquid enthalpy calculation method, you can select one of the following thermodynamic methods or continue to use the system calculation method.

Equations of state

• GERG-2008 equation of state

  Important: The GERG-2008 equation of state in AVEVA Process Simulation is currently in an experimental state.

• LK — Lee-Kesler equation of state

Generalized methods

• Library correlations
