| Research Abstract |
Tidal stream distribution in Obatake strait was observed for electricity generation. There are 3-dimensional flows near a bridge's piers due to complicated geography of the strait and the existing piers. Depth-ward reducing of the stream isn't so much. So, the strait has 5 times higher energy than expected and a turbine can be set deep without a loss.
Various Darrieus water turbines' properties were investigated. To improve their difficulty of starting revolution, assist experiment was carried out. It resulted in helping well starting revolution to harness low stream power efficiently. Expecting electricity was estimated from these results. Only flow speed of the tide in Obatake which explains the observed tide could be calculated by CFD.
