Substantial growth in wind energy capacity is essential to meeting global mid-century net-zero carbon emissions targets. As wind turbines scale up and expand into offshore environments, they encounter operating conditions where traditional aerodynamic models often fail: high-thrust regions and yaw-misaligned winds. By leveraging a first-principles approach, the recently developed Unified Momentum Model (UMM) circumvents the limitations associated with the empirical corrections applied to the classical momentum theory-based models to predict rotor dynamics under these operating conditions. Replacing classical momentum theory, the UMM can be coupled with a traditional blade element model to obtain a Blade Element Momentum (BEM) that works across all operating regimes without empirical corrections.
