Martin Schiemann | Ruhr-University Bochum, Germany
Dr. Schiemann started his career at Ruhr-University Bochum in the department of physics. After having achieved his diploma, he moved to the faculty of mechanical engineering to join the Department of Energy Plant Technology, where he finished his PhD on spray roasting processes. Since 2012, his work group investigates different thermal processes with a focus on reacting particles. The reduction of carbon emissions is one of the leading aspects in his research. Experiments from the laboratory scale up to semi-industrial devices are the methods of choice, accompanied by computational fluid dynamics simulations of laboratory and full-scale industrial plants. Pulverized biomass combustion in conventional and oxy-fuel atmospheres is one of the core topics of his work, but alternative fuels like different waste materials and metal fuels are also part of the portfolio. Spray roasting of metal chlorides, a class of waste materials from processes like steel pickling or battery recovery, is not just a disposition process, but recovers valuable metal oxides with different functionalities. Radiative heat transfer plays a decisive role in many processes involving reacting particles. Experimental investigations and numerical consideration of micrometric to macroscopic particle systems provides information on and tools for radiative heat transfer consideration in high-temperature systems. Prof. Schiemann teaches different subjects related to carbon capture and utilization, supply streams and disposal of materials from energy plants and material conversion in high-temperature processes.

Dimitrios Karamanis | University of Patras, Greece
Professor of Alternative Energy Sources at the
Department of Environmental Engineering of the University of Patras. He
studied Physics at the University of Ioannina (1986-1990) where he submitted
his doctoral thesis (1990-1997). With Postdoctoral Fellowships at CEN
Bordeaux (Marie Curie 1999-2001) and at the University of Ioannina (Marie
Curie 2001-2002 and until 2008), Prof. Karamanis has thirty years of
research experience in the fields of alternative energy sources with special
emphasis on wind and solar energy utilization technologies in the last
decade. Participating in competitive National and International research
programs as scientific coordinator and researcher, he has published over 110
scientific papers in scientific journals, patents and chapters in books with
>3000 citations and h-index 35 (Scopus). Prof. Karamanis teaches courses on
renewable energy sources, energy efficiency and RES applications in
Departments of the Universities of Ioannina and Patras since 2006.
