Three-dimensional computational fluid dynamics (CFD) has been carried out in order to investigate the effects of endplates on the performance of straight-bladed vertical axis wind turbine. The computational wind turbine model has two blades; the rotor diameter is 0.75m; the blade span length is 0.5m; the blade chord length c is 0.08m. The endplate is assumed to be an airfoil-like shape, which outline is larger than the blade section by length of s. The results of the CFD showed that the endplates with s/c = 6.25% give almost no influence on the condition of tip vortex shedding. However, the power coefficient increases about 8.1 % due to the endplates.
