摘要

摘要: 通过物理模型试验,统计分析得到了无结节网衣的水阻力系数在不同状态下随雷诺数、倾角和布置状态的变化规律,并通过网衣沉子的组合试验验证了所得经验公式的正确性和适用性,为深水网箱等渔具的水动力计算提供了依据.

Abstract: On the basis of the hydrodynamic experimental results, the effects of Reynolds number, flow direction to the net,and net setting status on the drag coefficients of no deless plane fishing net were studied.According to the experimental results, empirical formulas of the drag coefficient were achieved and their validity was verified through a specific experiment of net-weight system.The results are useful to the hydrodynamic calculation of fishing gears such as deep water sea cage, and so on.
