摘要

铜合金网由于具有较好的抗生物污染和耐腐蚀性能，在海洋养殖中越来越受到重视。本文通过一系列室内试验研究了链式合金网在波浪中的水动力特性。为了研究上游铝合金网的屏蔽效果，测量了上游铝合金网在下游不同位置的波浪高度和作用在下游网板上的波浪力。推导了不同波高、波周期和浸没深度下的透射系数和屏蔽系数。实验数据表明，无论是单网还是两网平行放置在水中，波浪透射系数在1（1 ± 0.04）附近波动，屏蔽系数在不同条件下也在1（1 ± 0.07）附近波动。这两个系数与网板浪高、波周期和浸没深度的相关性较弱。这表明这种金属网的屏蔽作用可以忽略不计。为了通过试验数据获得经验水动力系数，提出了一种用户友好的数值优化方案。优化后的水动力系数能较好地预测框架和网架上的波浪力。

Hydrodynamic characteristics of the aluminum alloy net panel in regular waves: An experimental study

Copper alloy nets have attracted more and more attention in marine aquaculture, due to their better performance to resist biofouling and corrosion. In the present study, a series of laboratory experiments are conducted to investigate the hydrodynamic characteristics of the chain-link type alloy nets in waves. The wave elevations at different downstream locations of the nets and the wave forces on the downstream net panel are measured to investigate the shielding effects of the upstream aluminum alloy nets. The wave transmission and shielding coefficients under different wave heights, wave periods, and immersion depths are derived. The experimental data show that the wave transmission coefficient fluctuates around 1 (1 ± 0.04), whether only a single net or two parallel nets are placed in water, and the shielding coefficient also fluctuates around 1 (1 ± 0.07) under different conditions. Both two coefficients have weak correlation with wave heights, wave periods and immersion depths of the net panel. It indicates that the shielding effects of such metal nets are negligible. To obtain the empirical hydrodynamic coefficients through test data, a user-friendly numerical optimization scheme is developed. The optimized hydrodynamic coefficients can well predict the wave force on the frame and the nets.

期刊介绍： Aquacultural Engineering is concerned with the design and development of effective aquacultural systems for marine and freshwater facilities. The journal aims to apply the knowledge gained from basic research which potentially can be translated into commercial operations. Problems of scale-up and application of research data involve many parameters, both physical and biological, making it difficult to anticipate the interaction between the unit processes and the cultured animals. Aquacultural Engineering aims to develop this bioengineering interface for aquaculture and welcomes contributions in the following areas: – Engineering and design of aquaculture facilities – Engineering-based research studies – Construction experience and techniques – In-service experience, commissioning, operation – Materials selection and their uses – Quantification of biological data and constraints
