Experimental investigation on the relationship between sluice caisson shape of tidal power plant and the water discharge capability

Experimental Study on the Discharge Characteristics of Sluice for Tidal Power Plant

“…The experimental results showed that the average discharge coefficient ranges from 1.3 to 1.47, which was approximately 30% smaller than the value obtained from the similar previous experiment (Lee et al, 2010) performed in a two-dimensional open channel. This difference was presumed to be influenced by the two factors with regard to the change in bottom topography and the dimensional effects in lateral direction.…”

“…It is clearly seen that the values showed no significant functional relationship with the head difference. On average, the discharge coefficient ranged from 1.3 to 1.47, which was apparently smaller than the values of the same quantity obtained from the previous study (Lee et al, 2010), where the coefficient was mostly greater than 2.0. The reason for this substantial discrepancy is ascribed to the difference between the experimental conditions of the two experiments.…”

“…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 1.47. These values were substantially smaller than those obtained from the previous study performed in a two-dimensional open channel (Lee et al, 2010). As the previous study had some limitations in reproducing the bathymetric and flow conditions in the field, it is more recommended to use the results acquired in the present experiment.…”

“…The main role of the sluice is introducing as many waters through it so as to achieve target capacity of the power generation. In this respect, Lee et al (2010) investigated the characteristics of water discharge according to geometrical shape of the sluice in order to maximize the water discharge performance of the structure. Their study had some limitations in evaluating the performance of the sluice as they made experiments with a single sluice caisson in a two-dimensional open channel.…”

Effect of Intake Vortex Occurrence on the Performance of an Axial Hydraulic Turbine in Sihwa-Lake Tidal Power Plant, Korea

“…Lee at al. [11] experimentally investigated the relationship between the sluice caisson shape of a tidal power plant and the water discharge capability. Peng et al [12] used the multi-objective constrained optimization method to minimize the total hydraulic loss and the cavitation coefficient of a runner blade in an axial hydraulic turbine.…”
