There is still discrepancy regarding the verification of CFD U-RANS simulations of vertical-axis wind turbines (VAWTs). In this work. the applicability of the Richardson extrapolation method to assess mesh convergence is studied for several points in the power curve of a VAWT. A 2D domain of the rotor is simulated with three different meshes. https://www.alarecre.com/Disney-The-Nightmare-Before-Christmas-Lock-Shock-and-Barrel-Art-AirPods-Pro-2nd-Gen-Skin-p101716/
