Regeneration of Complex Capital Goods (Hardcover)

This open access book compiles the groundbreaking research conducted by the Collaborative Research Center (CRC) 871, centered around the "Regeneration of Complex Capital Goods." This comprehensive work unveils an array of innovative methods developed through CRC 871, designed to revitalize and enhance the functional attributes of these critical assets. From non-destructive characterization of heavily stressed turbine components to the dynamic behavior of regenerated structural elements, each chapter offers a meticulous exploration of diverse facets in the field. The book also addresses the crucial consideration of variability in repair processes and material properties, as well as the comprehensive control of regeneration processes. With insights into simulation-based process design, fast measurement techniques, and resilience-based decision criteria, this volume provides a comprehensive view of the cutting-edge approaches employed. Moreover, readers will find a detailed process chain for condition-based regeneration, offering a practical framework for implementation. Finally, the book sheds light on the importance of targeted public relations in disseminating the invaluable research carried out by Collaborative Research Center 871. This extensive compilation not only showcases the scientific rigor behind maintaining complex capital goods but also demonstrates the collaborative efforts that brought together experts from various fields to push the boundaries of regeneration technology.

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 ofthe Collaborative Research Centre 871 “Regeneration of Complex Capital Goods”.
