Consultancy Service

Risoe has implemented the noise prediction model developed by Brooks, Pope and Marcolini at NASA and the model is also a part of the HAWTOPT rotor design program and in this way it is possible e.g. to design a rotor with constraints on noise

The Aeroelastic Design Programme offers to and has experiences with performing aeroelastic stability analyzes of three-bladed wind turbines for the industry using the tool HAWCStab.

Consultency services related to aero/hydro/servo-elastic response of wind turbine of are offered. Essentially for this service is the use of the aeroelastic tool HAWC2.

An airfoil/blade section profile design tool, AIRFOILOPT, has been developed at Risø. This tool uses the flow solver XFOIL or the in-house 2D CFD code, EllipSys2D, in combination with numerical optimisation

Based on the airfoil/blade section profile design tool, AIRFOILOPT, developed at Risø three airfoil families have been designed at Risø. The three designs have been documented in the Velux Open Jet facility and by using the computational tools XFOIL and the in-house CFD code, EllipSys2D

Electricity market and power system analysis based on detailed power system models

Analysis of potentials, integration and economy of new energy-technologies. For example the potential, integration and economy of bio-fuels in the Danish/European energy system.

Specialist assistance is offered within analytical chemistry.

A blade and wind turbine design tool, HAWTOPT, has been developed at Risø. This tool uses common rotor aerodynamic models, but also more advanced models such as CFD models in combination with numerical optimisation. The tool can as well be coupled to aeroelastic models so that the design can be based on aeroelastic response

Design & implement tailor-made CDM capacity building programs. Design and produce training manuals, case studies, guidebooks. Advice national CDM offices. Organize & implement training on CDM project development.

New and innovative energy crops and cropping systems are needed with specific interest for bioenergy purposes. Assumptions about technological development and energy use throughout the conversion processes are considered.

Together with MEK at DTU, the Aeroelastic Design Unit is running the WEB-database “Database on Wind Characteristics”. The purpose of the database is to provide wind energy planners, designers and researchers, as well as the international wind engineering community in general, with a source of full-scale wind field data (time-series and resource data).

The Guidelines for Design of Wind Turbines is a complete handbook covering the aspects of wind turbine design. It is an essential tool for anyone involved with wind energy.

At Risø DTU’s test station for large turbines at Høvsøre, mega-watt wind turbines are being tested.

Utilization of nutritional residues from bioenergy conversion by the agroecosystem - management and nutrient conservation

Risø DTU offers consulting services to clients world-wide. Since 1980 Risø DTU has participated in numerous international wind energy projects and technology transfer activities. The staff has extensive experience and knowledge in wind power, developed through decades of research.

Impacts on the development of renewable energy and the intensity of agricultural land use need to be taken into account when assessing the overall environmental benefits.

In connection with erecting wind turbines in mountainous or complex terrain there is a large need for knowledge of the local terrain induced wind

The Velux wind tunnel has a cross section of 7.5 x 7.5m and a length of 10.5m. The cross section of the jet blowing into the test section is 3.4 x 3.4m. The maximum flow velocity is 40m/s and the turbulence intensity at the test section inlet is 1%

In connection with the design of new wind turbine rotors Risø can offer a verification using the CFD code EllipSys3D

The Aeroelastic Design Unit, together with The Meteorology Unit, are currently developing a wind simulation package aiming at supplying wind turbine designers with a tool for generation of synthetic wind fields for aeroelastic design computations.
