The first objective of the work was to compare the aerodynamic loads and performance predicted by the double-multiple-streamtube model with the viscous-flow-field analysis of a vertical-axis wind turbine. Second, to check the validity of the two performance/load models, their predictions were compared with available experimental data. When the dynamic effects at low tip-speed ratios (dynamic stall) and added mass and circulatory effects at high tip-speed ratios were included, significant improvement was obtained in the prediction of the aerodynamic characteristics of the turbine, such as induced velocities and instantaneous blade forces. 11 references.
