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。
In this paper, the flow field of the rippling fissures generated on the coast of single-grooved sand dam is experimentally studied, with the focus on the changes of the horizontal shape of the flow field and the maximum fissure flow rate under different wave conditions. Experiments were carried out in a wave flume. Regular waves were used as incident waves. Wave height and velocity data were collected intensively in the entire field using a high-precision wave-height array and a flow meter array. Experiments were performed to obtain the full audience Wave height, average water surface and flow velocity distribution, the rivulet flow and the two existing compensating flows are described. The influences of different wave height on the flow intensity and the whole flow field are compared and analyzed respectively. The relationship between the maximum offshore flow velocity and the wave height The relationship was analyzed.
