偏流板付クロスフロー風車の実用化に伴うスケールアップに関する予備的検討

抄録

For performance improvement of cross-flow wind turbine for small size wind power generation, a casing (Dual Flow Deflector Casing) with two flow deflector plates and tail plate was devised. The two flow deflector plates are to improve ambient wind environment of the wind turbine and the tail plate is for attitude control of the casing to face toward the wind. In this preliminary study, to investigate the effect of size of wind turbine, by using two types of small size wind turbine test models with different diameters (114 mm and 171mm respectively), The performance tests of these wind turbines with/without the casing were done. As a result, each size of wind turbine with the casing showed higher performance than that without the casing.
