WebOct 15, 2024 · Vertical-axis turbines have been facing major challenges in establishing themselves in the renewable energy scenario if compared to horizontal axis turbines. The main reason is related to the relatively lower efficiency due to the intrinsic functioning principle, as they can reach power coefficients up to 30–50%. WebNov 1, 2024 · The turbine has a diameter d T of 0. 4 h and a blade height of 0. 3 h. This yields a size ratio to the building which is representative for VAWT installations on one to three storey buildings (see Section 1). Its blades consist of two overlapping semi-circles. The overlap helps to decrease the starting torque (Kumbernuss et al., 2012 ).
