Property Methods and Correlation Profiles

The following table lists the methods and correlations used by the Property Packages to do the requested calculations. Thermal and transport properties are calculated using experimental data when available.

Details about the thermodynamic methods and correlations used by DWSIM can be found in the Technical Manual (PDF document).
