Thermal Process Engineering
acting head Prof. Dr.-Ing. Antje Spieß
Goal of our research is the development of engineering models that can be safely applied in the practical life of engineers in industry and which allow the reliable design of thermal unit operations with minimal effort. We are convinced that the development of such models that represent a significant step forward as compared to currently available models is only possible based on a quantitative understanding of the interplay of phenomena on different size scales. The size scales we are investigating in our group thus reach from the molecular level to technical equipment. more
