ABSTRACT

This paper investigates wave-current-structure interaction considering both the following and opposing current. Experiments were conducted in a wave flume to determine wave transformation characteristics (i.e. wave reflection, transmission, and dissipation) employing both regular and irregular waves propagating in the presence of smooth and rough breakwaters. Discrepancies in the wave transformation characteristics are observed between smooth and rough breakwaters with and without currents. Transmission coefficient differences between smooth and rough structures were 33% and 12% for the regular and irregular waves, respectively. Reflection coefficients in irregular waves are more sensitive than in regular waves. However, the influence of external current on the energy loss coefficient was not significant when the submerged breakwater height increased.

摘要

本文研究了考虑跟随电流和反向电流的波-电流-结构相互作用。在波槽中进行了实验，以确定波转换特性（即波反射、传输和耗散），使用在光滑和粗糙防波堤存在的情况下传播的规则和不规则波。在有和没有水流的光滑和粗糙防波堤之间观察到波浪变换特征的差异。对于规则波和不规则波，光滑结构和粗糙结构之间的透射系数差异分别为 33% 和 12%。不规则波中的反射系数比规则波中的反射系数更敏感。然而，
