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, Faculty of Mechanical Engineering, Department of Technical Thermodynamics, presented a newly developed calculation equation for the dynamic viscosity of isobutane. His work was based on very precise measurements of this material property during his doctorate at the University of Rostock. As part of his subsequent research activities as an academic assistant at the Zittau/Görlitz University of Applied Sciences, Dr. Herrmann then worked on the creation of these calculation equations using the new experimental results obtained previously. The new viscosity equation for isobutane will be included in the next revision of the international database of the American Institute of Standards and Technology (USA) as a reference equation for this important working fluid, as is already the case for the working fluids ethane, propane and n-butane. Isobutane is used as a refrigerant in refrigerators, for example, 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 the Zittau/Görlitz University of Applied Sciences, and Dr. Herrmann presented three posters on the latest research results from the department for the calculation of thermophysical properties of other industrially important working fluids. The venue of this conference alternates annually between the cities of Rostock, Izmir (Turkey) and Baku (Azerbaijan).
In the plenary part of the conference, Prof. Kretzschmar was honored for his achievements in the field of thermophysical properties and presented with a laudatory speech by Prof. Dr.-Ing. Egon Hassel, Chair of Technical Thermodynamics, University of Rostock.
