Steady Wind

Previous pageNext page

The steady wind test cases comprise a series of individual simulations, each of which has a constant wind speed between cut-in (3 m/s) and cut-out (25 m/s). The rotor is aligned with the incoming wind flow so there is no skew angle in the horizontal plane. Each simulation is analysed for a significant period, which ensures full dissipation of initial transients. Results are presented in the form of mean values at each wind speed, which are computed over the final 100 seconds of simulation time. The first three rows of plots present turbine performance metrics, the next two focus on the blade structural responses, while the final row considers tower loads.
