Abstract
In the present study, a model turbine with 1.5 m rotor radius is investigated numerically by means of CFD (Computational Fluid Dynamics). A \(120^{\circ }\)-model of the turbine under free stream condition is created and a grid convergence study is performed. As the real model turbine will operate in a wind tunnel with high blockage ratio, the influence caused by limited space is analysed. Therefore, sectional loads along the blade radius, global loads as well as the axial induction and the effective angle of attack are investigated.
