Abstract
The discharge characteristics of sluice caisson for tidal power plant were investigated by carrying out a physical experiment in a planar open channel. The experiment was performed by installing 10 sluice models whose scale was determined to be 1/70 of the prototype in the planar open channel, where apron sections were made in front of and behind the sluice models to reproduce the condition in the field. The locations and method of measuring water levels were carefully determined so as to accurately estimate the discharge performance of the sluice caisson. The experimental results for various conditions of flow rates and water levels showed that the discharge coefficient of the sluice caisson was in the range of 1.3 to 1.4. Meanwhile, the velocity distribution in the wake of sluice caisson was also measured, from which it was found that velocities were 2~3% faster at the sluices near the central region whereas 4~5% slower at the sluices on both sides, compared to the mean velocity of the ten sluices.ed to be 1/70 of the prototype in the planar open channel, where apron sections were made in front of and behind the sluice models to reproduce the condition in the field.
