    Power Coefficient for Large Wind Turbines Considering Wind Gradient Along Height by Saroj Biswas, Jim Shih-Jiun Chen

    Published 2025-02-01
    “…This paper derives a new power coefficient for large wind turbines based on the power law exponent model of the wind gradient and height. The proposed power coefficient is a function of the size of the rotor disk and the Hellmann exponent, which describes the wind gradient based on wind stability at various locations, and it approaches the same value as the Betz limit for wind turbines with small rotor disks. …”
