For the calculation of the thermophysical properties of hydrogen, i.e. the thermodynamic and the transport properties dynamic and kinematic viscosity, thermal conductivity, Prandtl number, thermal diffusity and surface tension of hydrogen, a comprehensive software package is available as Windows DLL and Excel Add-In, which corresponds to the software FluidCal for the substance hydrogen (with SUBNR 45). The fundamental equation of state of Leachmann et al. [1] is used to describe the thermodynamic properties of hydrogen, while the viscosity of hydrogen is calculated on the basis of the equation of Muzny et al. [2] and the thermal conductivity of hydrogen is calculated on the basis of the equation of Assael et al. [3].
Because of the outstanding importance of "green" hydrogen research in addressing the man-made climate crisis, the software for calculating the thermodynamic and the transport properties of hydrogen is provided free of charge to universities and research institutions financed primarily by public funds, if the software is used exclusively for teaching and research.
In order to receive the software, the staff member of the chair, institute or research institution may send an e-mail to the contact address listed below confirming that the software is to be used exclusively in research or teaching. If students need the software for work during their studies, the order cannot be placed by the students themselves, but only by the supervising person.
The e-mail should contain the exact name of the respective institution with postal address, telephone number and e-mail address. In our reply we will send our terms of use for the FluidCal software of hydrogen, and after receipt of the signed terms of use, the software for calculating the thermophysical properties of hydrogen will then be sent to you as an encrypted 7z archive.
Detailed informations with application examples for the FluidCal software are described here. Further information on the entire software range can be found at https://www.thermo.ruhr-uni-bochum.de/thermo/wagner.html.en. The software is distributed by the Engineering office Dr.-Ing. N. Kurzeja.
