암초형 월류구조물의 월류특성 분석

Abstract

Waves coming from offshore can be amplified, swashed and overtopped by a wave overtopping control structure, and it converts the kinetic energy of the waves to the potential energy with a hydraulic head above the mean sea level by conserving the overflow in a reservoir. Then the potential energy in the form of hydraulic head can be converted to electric power utilizing extremely low-head hydraulic turbine. This experimental study aims to find the most optimal shape of a reef-type wave overtopping structure as a wave energy converter. Laboratory experiments for the performance evaluation of wave overtopping control structures were carried out in three dimensional wave tank. As a results, we know that the optimal shape of the reef-type structure in order to promote the wave overflowing have straight guide vanes and deeper draft.
