Application of Richardson extrapolation method to the CFD simulation of vertical-axis wind turbines and analysis of the flow field
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 acupatch 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
