About the suitability of different numerical methods to reproduce model wind turbine measurements in a wind tunnel with a high blockage ratio

Abstract

The paper describes the experimental and numerical investigation of a model wind turbine with a diameter of 3.0 m in a narrow wind tunnel. The objectives of the study are the provision of validation data, the comparison and evaluation of methods of different fidelity and the assessment of the influence of the wind tunnel walls. It turned out, that the accordance between the experimental and numerical results is good, but the wind tunnel walls have to be taken into account for the present setup.
