Galathea og kulstofkredsløbet
I kulstofprojektet er det Risøs opgave at måle udvekslingen af CO2 og partikler mellem havet og atmosfæren samt måle koncentrationen af partikler i atmosfæren. Viden om havets evne til at optage eller afgive CO2 er vigtigt for at kunne forudsige hvordan klimaet udvikler sige. På samme måde har partikelkoncentrationen og partiklernes bevægelse afgørende betydning for vejr og klima. Her kan du læse hvilke data Risøs forskere fik under Galatahea-togtet.

Monitoring and Advanced Control of Three Phase DPGS Project
The renewable energy sources such as wind turbines, solar, fuel-cells, micro-hydro-turbines, etc. are more and more used as an alternative to the traditional resources. Since their usage is rapidly increasing in the recent years, the need for stable and performant grid-interface converters is becoming very actual. As the penetration of renewable energy is still increasing, stricter demands for grid-connection are coming up.

The Bolund Experiment

The Bolund experiment is a field campaign that provides a new dataset for validating models of flow in complex terrain. It has been the basis for a unique blind comparison of flow models. An increasing number of wind farms are being installed in complex terrain where wind resources are good, but the wind shear and turbulence can exceed the design basis. CFD is becoming a standard tool to quantify such wind conditions and determine the optimum positions of the wind turbines. However, these flow models have usually only been validated against wind tunnel experiments with simple terrain forms.

Structural Blade Design and Testing
With the explosive growth within wind energy, more research is needed in the area of structural design and testing of wind turbine blades. When the blade design is up-scaled without optimization, its weight increases cubically with respect to the performance. Therefore it is crucial to optimize the design of  future blade. The main focus is to try to understand why and where the blades fail and then improve the design accordingly. A combination of experimental and numerical studies is used to address the most critical failure mechanisms observed during full-scale tests and the corresponding FE-analysis.

Analysis and modeling of unsteady aerodynamics with application to wind turbine blade vibration at standstill conditions
Since the introduction of computational models for the dynamic aeroelastic response of wind turbines, numerous dynamic issues have been investigated to assist in understanding and overcoming problems as well as help designing reliable turbines. In some cases specific problems have necessitated evolution of new or improved sub-models in the aeroelastic computational tools, such as for instance the so called dynamic stall models that models the dynamic aerodynamic response from the onset of separation until the flow over the airfoil is fully separated.
