WebAug 19, 2013 · The performance of the VAWT under fluctuating winds was investigated and results show a dependency to wind speed. Increasing wind speeds cause blade lift to increase more rapidly than drag... WebFeb 20, 2024 · For this purpose, the vertical component of the fluctuating wind speeds in the wake of Model 2 (Figure 1(b)) was measured. The experimental setup for this measurement with the use of hot wire was the same as described in Section 3 , with the same inclination angle and yaw angle; that is, α = 25° and β = 30°.
