Institut für Technische Thermodynamik
Institute for Technical Thermodynamics
The research interests at TTD concentrate on experimental and theoretical-analytical investigations of complex heat and mass transfer processes as well as the analysis of energy systems. Our expertise reaches from the description of nano- and micro-scale transport phenomena to macro-scale and engineering applications.
Peter Stephan,
Head of the Institute
Thermodynamics is an important basic science for many areas of mechanical engineering and beyond. It describes the transport and conversion of different forms of energy and the associated material properties.
