文摘

CFD study to characterise the dynamic behaviour of a Savonius vertical axis wind turbine. URANS modeling approach with k-ω SST turbulence model in OpenFOAM code. Analysis at different TSR and angular speed of rotor at constant wind speed. Over-estimation of experimental data with 2D approach, good agreement with 3D approach. Evaluation of influence of the rotor height on fluid dynamics and power coefficient.
