Annual Review Page 4 DTU Mechanical Engineering Annual Report 2008 Page 5 Introduction The start of 2008 was also the start of the new Dept. of Mechanical Engineering which was a re- sult of the expansion and reorganization of DTU. Two new groups, Manufacturing Engineering together with Materials Science and Engineering supplemented the existing activities including Solid mechanics, Fluid Mechanics, Energy Engineering and Coastal, Maritime and Structural Engineering resulting in a strong team covering the field of mechanics and materials. The very positive results from the first year in the new department have shown that the reorganization has been a success. The subject areas of the department covering mechanics, manufacturing engineering, energy engineering and materials are the basis for a considerable part of the Danish industry. Dept. of Mechanical Engineering is aware of their responsible for the supply of young engineers and research results to Danish industry, and a close co-operation with national and international partners has a high priority. An important event in 2008 was a two day seminar at Hotel Hvide Hus in Køge where all em- ployees were invited. The objective of the seminar was to get to know each others and to discuss values, strategy and professional content of the new department. More than 130 employees participated in the seminar and the response has been very positive. The department managing group decided from the beginning to follow an offensive strategy in the implementation of a new procedure of PhD-funding, where the responsibility for the distribution of PhD-funds was transferred from the DTU-dean of Research to the departments. 30 new PhD-projects were initiated in 2008 with an external co-funding of more than 80% which more than meet the goal defined by DTU. A consequence of the reorganization of DTU was that a service check of the educations was needed. A “task force” referring to the Head of Education was appointed and the first result of their work is presented including proposals for recommended study plans and revised bachelor and master programs. We are convinced that the revised study plans will increase the number of skilled students who chose to study at Dept. of Mechanical Engineering. At the end of 2008 the budget ended up to be more tight than expected. However, Dept. of Mechanical Engineering is now well trimmed for the coming challenges and we are looking forward to continue the co-operation with industry and universities all over the world.

The prize was Systems at DTU Mechanical Engineering received in June an presented by HRH Crown Princess Mary. award for his master thesis project.

The award was presented at a ceremony in Milan and professor-ole-sigmund-1) In Danish included 1000 €. The master thesis was entitled “Design and modeling of a methanol plant for the REtrol vision” and was about computer modeling of the energy flows in a methanol plant. The model used biomass and electricity from wind turbines as main energy inputs for the methanol production. Seabed and Wind Fram Interaction Ocean Energy Research Programme This is a four-year (1/1, 2008 to 31/12, 2011) research program, An ocean energy research programme, “Havenergiprogrammet”, undertaken jointly by Technical University of Denmark, DHI was funded by the Norwegian power producer Statkraft to Water & Environment, University of Aalborg, LICengineering promote Nordic research in offshore wind power and wave and the University of Dundee, funded by Danish Council energy.
