Acoustic measurements will be performed at various degrees of wake using several measuring techniques. The results will be compared with aerodynamic measurements to enhance knowledge of wind turbine
The project involves the final process design of a full-scale plant for continuous prodiction of second-generation bioethanol based on results from the IBUS pilot plant, where straw is the basic
In this project, by means of computer simulations, flow conditions of wing tips were investigated for a number of wing designs for wind turbines. Various numeric design methodologies were developed
For the first time ever, this project integrated three design areas in a simulation: electrical design and
optimisation of wind turbines (generator and gearbox), aerodynamic design (material and
The project aims to enhance current knowledge of how temperature and pressure during the production process and the water content of biomass affect pellet quality, and of the mechanical properties of
This project developed methods and tools for modelling various ruptured wind turine blades and for analysing the residual strength of the blades if they crack. This provides a foundation for assessing
This project involved the first two phases in establishing a knowledge centre for wind turbine components. In the first phase, the knowledge centre was officially established, and it was decided that
The project aims to provide the necessary basis for deciding to establish a knowledge centre promoting Danish innovation in the field of wind turbine components. The purpose of the tesst centre will
The project endeavoured to calculate electricity generation costs in modern onshore wind turbines. At average operating costs of DKK 0.08/0.10/kWh, production costs per kWh can be calculated at DKK 0
Through contacts to key players in the biofuels market, various means and policies are considered to identify the most apporpriate package solutions. The results will be used by the European
To extend the life of gear oil - not least for use in offshore wind turbiens - the project aims to investigate whether nano-filtration using CJC filters (cellulose fibres) with zeolites eliminates the
The project constituted a phase of the strategic partnership between Risø DTU and the wind turbine industry on developing an aeroelastic design complex. The project worked with the following issues
IEA task 42 identifies existing biorefineries and process potential, prepares common definitions and standards for classifying and assessing technical, financial and environmental advantages and
Methods are devised for online control of biofuel pellet quality using, for instance, mechanical durability, fine particles, pellet density and length and particle size as parameters. The new methods
The project enables Denmark to resume its activities in the IEA implementing agreement on hybrid and electric vehicle (IA-HEV), dealing with, for instance, electric cars with batteries and fuel cells
These two projects continue the publication of the eight-page news magazine Bioenergy Research with six issues a year. The magazine goes over new research results and features debate-triggering and
One of the current topics of the IEA’s cooperation on research in fuel wood chips is forecasts of fuel resources, technical production, wood fuel transport, valuation, long-term storage of decomposed
Aalborg University and Risø/DTU have developed a model to estimate responses and structural reliability of wind turbines under normal operation. Various Monte Carlo simulation algorithms were tested
Process optimisation is performed at the MaxiFuels pilot plant at DTU in the context of, for instance, membrane distillation of ethanol, separation of the permanent residual fraction from glucose
