Software for the IAPWS-95 Formulation (H2O)

For the description of the IAPWS-95 formulation including its range of validity and its accuracy see here

There is an extensive software package available for the use of IAPWS-95. This package is available as the software FluidCal in the version for the substance water (SUBNR 50).

Due to the scientific relevance of IAPWS-95, the software for the calculation of thermodynamic properties of water based on IAPWS-95 is available for universities free of charge provided the software is used for pure teaching and research purposes.

In order to receive the software, a co-worker of the institute, chair, or working group should send an e-mail to the contact person. The e-mail should confirm that the software is only used for teaching or research purposes. Passing on the software in any form is not permitted. The person who orders the software should have a permanent position (e.g. professor or senior researcher). If students need the software for works within their study, the software cannot be ordered by the student, but only by the supervisor.

The e-mail should contain the name of the respective institution with the postal address, telephone number, and e-mail address. The reply will be given as to how the software can be obtained.

The software FluidCal is distributed by the Engineering office Dr.-Ing. N. Kurzeja.

Please note that equivalent software packages for the reference equations of state GERG-2008 and IAPWS-IF97 are also available. Further information on the entire software range can be found at https://www.thermo.ruhr-uni-bochum.de/thermo/wagner.html.en.
