- •
Study of a bevel gear dynamic behavior in non-stationary regime is investigated.
- •
2D CFD model is validated with experimental results to introduce the transient aerodynamic load.
- •
The influence of rotating speed on the Darrieus turbine dynamic behavior is obtained.
- •
The rotational speed affects significantly the aerodynamic performance.
- •
The best performance according to power production and bearing vibration was achieved.
