【摘要】 利用模型试验对单片网衣在波浪条件下的水动力特性进行了研究。其结果表明Kc数对网衣速度力系数的影响很小,但网衣密实度对其影响相对较大。同时,和网衣所受速度力相比,惯性力项很小,可以忽略。实验研究结果为数值模拟中水动力系数的选取提供了有力的依据。更多还原

【Abstract】 In this paper, model test is carried out to get knowledge for the hydrodynamic characteristics of plane nets in wave. The experimental results indicates that the effect of KC number is small on the drag force coefficient Cd of submerged fishing nets, but the effect of the net solidity S is evident Relative to drag force, the inertia force is small and can be ignored in wave for fishing net. The results of model test give a good reference for the selection of drag and inertia coefficients for nets in wave.更多还原
