  • 본 연구에서는 물받이 형상이 조력발전용 수문의 통수성능에 미치는 영향을 평가하기 위한 수치모델링을 수행하였다. 수치모델링은 수문 구조물 자체의 형상은 변화시키지 않고 물받이 폭, 경사 및 수평구간 길이가 다른 경우에 유량계수 값의 차이를 비교함으로써 이루어졌다. 모델링 결과로부터 물받이 형상에 따라서 전반적인 통수성능에 유의미한 차이가 나타나게 됨을 확인하였다. 수문의 통수성능을 최대한 발휘하기 위해서는 수문 구조물 양 측면으로 수문의 폭 만큼 여유를 두고, 경사는 1:5, 수평 구간 길이는 수문 케이슨의 흐름방향 길이와 비슷한 50 m 정도가 되도록 물받이를 설계하는 것이 바람직한 것으로 분석되었다.

  • The change of water discharge capability of sluice caisson for tidal power plant according to installation of the rubble mound was investigated by performing laboratory experiment. The experiment was carried out in an open channel flume with a great care to measure flow rate and water level in the flume accurately. Eight different sluice caisson models were used in the experiment. The water discharge capabilities of seven sluice models decreased with respect to the placement of the rubble mound, while increased for only one sluice model. On average, the values of discharge coefficient decreased by approximately 10% when the sluice models were placed on the rubble mound. It is concluded that the shape of the rubble mound can affect the water discharge capability of the sluice caisson, so that its shape should be significantly considered in the design of the sluice caisson, especially when it is deployed in a site of relatively deeper depth.

  • An hydraulic experiment was carried out in an open channel flume in order to investigate the water discharge capability of the sluice caisson for tidal power generation, which greatly affects the economical efficiency of the construction of a tidal power plant. To predict the influence of change in the major design parameters relating to the sluice shape on the water discharge capability of the sluice, the experiment was carried out very precisely. The experiment was carried out for the six different sluice models of different widths and bottom heights of the sluice throat section. The experimental data showed that the water discharge generally increased by increasing the width of the throat section if the side shape of the sluice was the same. In addition, the coefficient of discharge was larger when the bottom height of the throat section was higher for the two bottom heights that were tested.
