潮位差を利用した海水交換システムの開発

抄録

In order to improve the water quality in closed water body like a port, various breakwaters with the seawater exchange function are studied and developed. The seawater exchange function of this case is using the wave energy. On the other hand, for the seawater exchange system using the tidal difference, it is necessary to operate the gate and measure the water level.
Then, authors designed the siphon type check valve. In this paper, the structure of this siphon type check valve is explained and the performance of this seawater exchange system involving this check valve is studied by a numerical analysis. From the results obtained by the numerical calculations, it was confirmed that this system with the siphon type check valve can apply to seawater exchange in a port.
