摘要
该文实验研究了单沟槽沙坝海岸上产生的波生裂流流场,重点关注了不同波浪条件下流场水平形态以及最大裂流流速的变化。实验在波浪水槽中进行,采用规则波作为入射波浪,应用高精度浪高仪阵列和流速仪阵列,在全场范围内较密集地采集波面升高和流速数据,通过分析实验数据,获得全场波高、平均水面以及流速分布,对裂流及两个存在的补偿流进行了描述,分别比较和分析了不同波高对于裂流强度及整个流场形态的影响,并对最大离岸流速与波高间的关系进行了分析。
A laboratory study on rip current induced by regular waves breaking of a sand bar incised with a single channel was conducted. The investigation focuses on dependence of the horizontal current pattern and maximum velocity on the incident wave. Regular waves are used in the experiments. Wave gage array and ADV array are respectively employed in order to get abundant data of surface elevations and mean-current field. The distribution of wave heights, mean water level and mean-current field are obtained in the experiments. Rip current and its feeder flow are described in detail. The influence of incident wave on rip current strength and flow pattern is analyzed. The maximum flow velocity is shown in a linear dependence on the incident waves.
