The annual international conference “Thermophysical Properties for Technical Thermodynamics,” which focuses on the thermophysical properties of working fluids, was held in Rostock this year. At the conference, Dr.-Ing. Sebastian Herrmann of the Faculty of Mechanical Engineering, Division of Technical Thermodynamics, presented a newly developed calculation equation for the dynamic viscosity of isobutane. His work was based on highly accurate measurements of this material property conducted during his doctoral studies at the University of Rostock. Subsequently, as part of his research activities as a research assistant at the Zittau/Görlitz University of Applied Sciences, Dr. Herrmann worked on deriving these calculation equations using the new experimental results he had previously obtained. The new viscosity equation for isobutane will be included as the reference equation for this important working fluid in the next revision of the international database of the American Institute of Standards and Technology (USA), as is already the case for the working fluids ethane, propane, and n-butane. Isobutane is used as a refrigerant, for example, in refrigerators and is an important component of natural gas. In addition, Prof. Dr.-Ing. habil. Hans-Joachim Kretzschmar, also from the Department of Technical Thermodynamics at Zittau/Görlitz University of Applied Sciences, and Dr. Herrmann presented the department’s latest research findings on the calculation of thermophysical properties of other industrially significant working fluids in three posters. The venue for this conference rotates annually between the cities of Rostock, Izmir (Turkey), and Baku (Azerbaijan).
During the plenary session of the conference, Prof. Kretzschmar was honored for his contributions in the field of thermophysical properties and was recognized in a laudatory address by Prof. Dr.-Ing. Dr. h.c. Egon Hassel, Chair of Technical Thermodynamics, University of Rostock, paid tribute to him in a laudatory address.
