Abstract:A numerical approach is proposed to simulate the interaction between flow and fishing net in steady current. The numerical approach is based on the joint use of the porous media model and the lumped-mass model. The configuration of flexible net can be simulated using the lumped-mass model and the flow field around plane nets can be simulated using the porous media model. Using an appropriate iterative scheme, the fluid-structure coupling problem can be solved and the steady flow field around flexible net is available. In order to validate the numerical approach, the numerical results are compared with the data obtained from the physical model tests. The comparisons show that both the configuration of the flexible nets and flow velocity results are in accordance with that of the corresponding physical model tests.
