建立了一个三维数值模型，对海流中平面渔网周围的流场进行了数值模拟。采用可实现的k-ε湍流模型描述流动，采用有限体积法求解控制方程。在该模型中，网络使用多孔介质模型建模。未知的孔隙系数是由网上的水动力和流速以及攻角使用最小二乘法确定的。为了验证数值模型的正确性，将数值计算结果与两个物理模型试验结果进行了比较。计算结果与实验数据吻合较好。该数值模型适用于渔网周围流场的模拟。本文用所提出的方法计算了不同网面倾角、网面高度、网面间距和网面数目时网面周围的流场。本研究提供了有关网箱周围流场的信息。
A three-dimensional (3D) numerical model is established to simulate the flow field around fishing plane nets in a current. The realizable k–ε turbulence model was chosen to describe the flow, and the governing equations are solved by using the finite volume method. In this model, the net is modeled using the porous media model. The unknown porous coefficients are determined from the hydrodynamic forces on the net and from the flow velocities and the attack angles using the least squares method. In order to validate the numerical model, the numerical results were compared with the data obtained from two physical model tests. The comparisons show that the numerical results are in good agreement with the experimental data. This numerical model is applicable for the simulation of the flow field around a fishing net. Using the proposed method, this paper presents the flow field around a plane net with different plane net inclination angles, plane net heights, spacing distances between two plane nets and plane net numbers. This study provides information about the flow field around the fishing net cage.
