Abstract

In this study, first, we adopted a twin configuration of a Darrieus hydrokinetic turbines that can bring about an improvement in efficiency through positive interaction and obtained the optimal shape through parametric analysis of the small-scale turbine model by computational fluid dynamic simulations. Next, the effect of performance improvement was examined for symmetrical and asymmetrical ducts. The results show that the asymmetrical duct that utilizes diffusion effects has a comparative advantage in terms of efficiency and drag over the symmetrical one. However, the advantage of the Darrieus turbine, which has flow-directional independency, is lost in the case of the presented configuration; thus, we introduced the idea of a passive yaw-controller that adapts to the variation of the flow-direction that does not require additional energy consumption. In conclusion, such efforts and adjustments to enhance the performance of the Darrieus turbine by utilizing the interaction and diffusion effects discussed in this study will be helpful in securing competitiveness against other types of hydrokinetic turbines.
