Wind energy optimization by numerical wind modelling E! 5150

Our vision - a new industry standard based on CFD WindSim AS established the Norwegian Wind Atlas in 1998. During this project the methodology in WindSim was set forth. WindSim is based on Computational Fluid Dynamics (CFD) a method for solving the three -Dimensional Reynolds Averaged Navier Stokes equations. WindSim can be used in complex terrain and with challenging climatologically conditions. Realizing our vision The current industry standard is easy to use; it is robust and fast in terms of simulat ion time. The CFD method has to improve on: user friendliness, robustness, speed and accuracy. With the Eurostars project we can realize our vision. The WPs are divided in three groups: 1) CFD innovations Synthesizing advanced simulation and remote se nsing results, actuator disk wake modelling (modelling of the reduced wind speed area downstream of a wind turbine) and production prognosis based on coupling with Numerical Weather Models are all examples of innovative use of CFD. These tasks are address ed in WPs 2 to 4. 2) CFD - the new industry standard An improved CFD application, handling the special requirements seen within the wind sector; will be developed. Robustness, speed and accuracy are issues addressed in WPs 5 to 8. 3) Validation WP 9 c oncerns validation, it will run through the whole project period.
