Abstract
So far, most tidal stream generators have been developed in three types: a horizontal axis turbine, a vertical axis turbine, and a flapping-type hydrofoil. The first two are operated by one-way rotation, but the last one is oscillated. The flapping system inspired by nature has attracted researchers due to its eco-friendly characteristics, applicability to shallow water, and nonconventional oscillating movement.
In this study, we propose a flapping tidal steam generator of a mirror-type dual configuration, and the effects of the configuration on their performance are investigated through the experimental analysis in a towing tank and numerical analysis by computational fluid dynamics simulation. Throughout the numerical and experimental studies, we found that the rear system in the dual configuration can extract power close to that of the front system with a short distance between them such as two chords and an optimum phase difference, 90°.
