主 题：Knotless netting Fluid structure interaction Deformation characteristics Flow field SST k-omega model
摘 要：Knotless polyethylene(PE)netting is widely used in fisheries because of its excellent hydrodynamic performance and low *** deformation and the surrounding flow field distribution play an important role in determining the hydrodynamic characteristics of netting in moving *** order to investigate the effect of solidity ratio and attack angle on drag,netting deformation,and flow field distribution through the netting,a fluid-structure interaction(FSI)model based on a one-way coupling combining the shear stress turbulent(SST)k-omega model and the large deformation nonlinear structural finite element model was *** results showed the difference between the parallel and normal drag forces found in the present numerical model and experimental flume tank data were 9.17%and 11.58%,*** mean relative error in the inclined hydrodynamic drag for different flow velocities and attack angles was 8.35%,6.69%,and 5.37%for the nettings 1,2,and 3,*** results show that the present numerical simulation based on FSI one-way coupling can be used to examine hydrodynamic forces on *** flow simulation results show that there is a noticeable flow velocity decrease through the netting and a rather large velocity reduction region downstream from the netting for different attack *** results reveal the existence of turbulent flow due to the netting *** was found that the equivalent stress and total deformation increase as the flow velocity increases and solidity ratio decreases.
