The CFDWind wind simulation model, presented by technicians from the National Renewable Energy Center–CENER–has been acknowledged as one of the best according to the results obtained in the so-called “Bolund Experiment”.

The Bolund experiment was organized by the Technical University of Denmark’s (DTU) Risø National Laboratory for Sustainable Energy and co-financed by Vestas, toward validating flow models in complex terrain. Risø DTU challenged modelers from all over the world to predict the wind on the Bolund hill, based on the free wind conditions on entry and given the relief of the terrain. Those accepting the challenge were mainly European, together with research centers and companies from Canada and India.

Over 50 models were presented, by the more than 80 experts from around the world, representing different research centers, universities and industry. CENER presented two models that were among the best when predicting the average velocity at the measurement points. According to Risø DTU’s rankings this was particularly true for sensors of over 5m, where the CENER CFD Wind 2.0 model achieved the best results with a global mean error of 4% in wind velocity simulation.
