A simple vortex model applied to an idealized rotor in sheared inflow [PDF]
Wind Energy Science, 2023 A simple analytical vortex model is presented and used to study an idealized wind turbine rotor in uniform and sheared inflow, respectively. Our model predicts that 1D momentum theory should be applied locally when modelling a non-uniformly loaded rotor ...
