파랑 에너지 변환을 위한 월파제어구조물의 월파량 산정 실험

Abstract

Wave energy has been considered to be one of the most promising energy resources for the future because it is pollution-free and abundant natural resource. However, since it has drawbacks of non-stationary energy density, it is necessary to change the wave energy into a simple concentrated energy in order to put it to good use. Progressive waves in a coastal area can be amplified, swashed and overtopped by a wave overtopping control structure, and by conserving the quantity of overflow in a reservoir, the kinetic energy of the waves can be converted to the potential energy with a hydraulic head above the mean sea level. The potential energy in the form of hydraulic head can be utilized to produce electric power as in hydro electric power generation. This study aims to find the most optimal shape of wave overtopping structure for maximum overtopping volume of sea water, and for this purpose, we carried out the wave overtopping experiment in a wave tank under both regular and irregular wave conditions.
