| Outline of Final Research Achievements |
Dammed type Darrieus Turbine with inlet nozzle is proposed for shallow flow in U-type sloped side gutter in the present study. The feasibility of Utilization and the operating characteristics are investigated with various slope angles of gutter. The followings are obtained as results. (1)It's obvious that 20 or 30 percents of total flow energy, which depends on sloped angle of gutter, can be extracted by the proposed turbine. (2)By appropriate selection of head evaluation, the same operating characteristics, being independent of sloped angles, appear. (3)There is optimum length of submerged blade-span for extracting high output power. (5) By installing the dammed type turbine in the sloped side gutter, the flow loss of hydraulic jump appears but the relation between turbine head and the loss have to be further investigated at present.
