Eckehard Specht [1] is a professor in Otto von Guericke University, Magdeburg, Germany. He belongs to Institute of Fluid Dynamics and Thermodynamics (ISUT) department. His specializations are Combustion technology, heat and mass transfer, chemical process engineering, global warming, and ceramic materials.

He has obtained his PhD in Heat transfer from TU Clausthal.[2] After that, he did the habilitation in the same university. He moved to OVG university, Magdeburg.

Background

Prof. Dr.-Ing. Eckehard Specht studied Chemical Engineering at the Technical University of Clausthal and was then Scientific Research Fellow at the Institute for Energy Engineering at the TU Clausthal (1977-1993). After his Ph.D. about the coal combustion (1984) and Habilitation in the field of high temperature process equipment (1993), he is professor from October 1, 1993 for thermodynamics and combustion at the Otto von Guericke University Magdeburg, Institute of Fluid Dynamics and Thermodynamics.

He is an appointed member of nine committees, including, the research community industrial furnaces of the Association of German Engineering Federation (VDMA), the Technical Commission of the German Ceramic Thermal Engineering Society (DKG) and the Committee of thermal processing technology by the German Iron and Steel Institute (VDEH). During his university career he was involved with a member of the Senate and Council of TU Clausthal (1983-1988), a member of the Senate of the University of Magdeburg (1994-2000) and since 1994 he is the Dean of teaching for the Faculty of Process and Systems Engineering of the Otto von Guericke University of Magdeburg.

On March of 14, 2003 he was awarded the Ludwig Mond Prize from the Institution of Mechanical Engineers, England.
