數値波動水槽를 이용한 透過性防波堤의 周邊波動場 解析에 관한 硏究

Abstract

Porous breakwater is used widely up to now because of several advantages that it can reduce wave run-up, reflected wave and wave pressure acting on structure. In this study, wave transformations by a porous breakwater and fluid velocity fields in and around the porous body are performed in the two-dimensional numerical wave channel based on the volume of fluid method(VOF

Hirt and Nichols, 1981). From the result of fluid velocity fields, confirmed that calm sea area happens behind breakwater by energy dissipation due to the wave breaking and fluid resistance in porous body and from the analysis of the spatial wave profile, investigated characteristic of wave transformation by form of porous breakwater.
