장주기 및 유동성분을 고려한 부유식방파제의 방파성능 개선

In this study, a series of laboratory experiments are carried out to analyze fluid behaviors around multi-arranged (2 pieces) float-ing breakwaters with various parameters such as distance between structures, wave periods and steepness. The rate of wave trans-mission is shown to be affected directly by wave periods of incident waves and the breakwaters with multi-arranged structuresshow the highest rate of wave protection compared with other cases. The velocity fields around the breakwaters are measured byusing the Laser Doppler Velocimetry system. The transmission coefficients are also measured in laboratory experiments. Finally,laboratory observed data are compared with numerical experimental results and analyzed in detail.
