Regeneration of Complex Capital Goods: Contributions to the Final Symposium of the Collaborative Research Center 871

Prof. Dr.-Ing. Joerg R. Seume:
Joerg R. Seume is Professor of Turbomachinery and Fluid Dynamics at Leibniz University Hannover, Germany. He received his Ph.D. in Mechanical Engineering for a NASA-sponsored research at the University of Minnesota in 1988 on ＂Laminar-to-Turbulent Transition in Oscillating Flow＂ as it occurs in Stirling engines. Previously, Mr. Seume completed his Master of Science in Mechanical Engineering at the University of Wisconsin in his native Madison in 1984. In industry, he worked as Research Engineer at Sunpower Inc. of Athens, Ohio, to develop solar powered Stirling engines. His career in gas turbines started when joining Siemens in 1991 where he went from the fluid mechanics laboratory to testing prototype gas turbines, a position of Project Leader in gas turbine development, and management positions in quality and production plant integration. In 2000, Dr. Seume accepted the professorship at Leibniz University Hannover focusing his research on unsteady effects in turbomachinery and wind turbines, including aeroelasticity and aeroacoustics. From 2010 to 2015, he served as Dean of the Faculty of Mechanical Engineering. Together with his team, he received the German Steel Industry’s 2018 Special Innovation Awardfor Climate Protection and Resource Efficiency, two ASME Best Paper Awards, and an IMechE Best Technical Paper Award.
Prof. Dr.-Ing. Berend Denkena:
Berend Denkena is Full-Time Director of the Institute and Chair of Production Engineering and Machine Tools at Leibniz University Hannover, Germany. After completing his doctorate with Prof. Hans Kurt Tönshoff on ceramic tools in 1992, he went into the machine tool industry as Design Engineer and later Head of various research and development teams at Hueller Hille in Germany and the USA. This company merged into today’s MAG IAS GmbH, now part of the Fair Friend Group, Taiwan. From 1996 to 2001, Denkena headed product development at GILDEMEISTER Drehmaschinen, now part of the DMG MORI Group. In 2002, after ten exciting years in industry, he returned to University of Hannover in the above-mentioned position. Denkena is an enthusiastic Scientist, Inventor, and Developer of machine tools and related technologies. His passion belongs to innovative concepts for machine tools including their further development toward more autonomy as well as future tools and manufacturing processes, and more recently solutions for a more sustainable manufacturing. Denkena is Member of CIRP, acatech, WGP, and Member of relevant supervisory boards.
Dipl.-Ing. Philipp Gilge:
Philipp Gilge graduated at the Leibniz University Hannover in mechanical engineering with focus on fluid mechanics. Since 2014, he has been working as Research Assistant at the Institute of Turbomachinery and Fluid Dynamics at the LUH. His fields of research have been the influence of roughness on the flows in turbomachines and flow measurement methods. From 2019 to 2022, he was Managing Director of the Collaborative Research Centre 871 ＂Regeneration of Complex Capital Goods＂.
