“…Overall, the degree of deceleration diminishes as the velocity increases, while this effect gradually becomes less pronounced with further increase in velocity. In particular, the velocity description of the cylindrical cage shown in Figure 11b is similar to that of solid cylinders [40,41], validating the reliability of the simulation. To illustrate the impact of the bottom net of the cage more clearly, we examined the bottomless single cage model, which was considered in previous numerical studies [42,43].…”

Ultra-high molecular weight polyethylene (UHMWPE) is a new kind of fishing gear material applied in deep-sea fishing cages, which is becoming a trend. Studies on the internal and external flow fields of cages made of UHMWPE have been scarce previously. Therefore, a three-dimensional numerical model for the UHMWPE cage is established herein, where the cage is modeled by a porous media model. The Darcy–Forchheimer coefficients of the porous media are obtained by physical model experiments and numerical simulations. Then, the cylindrical cage is divided into 16 planar nets circumferentially, along with an additional bottom net, to investigate its internal and external flow fields numerically. For a single cylindrical cage, the degree of deceleration decreases as the flow velocity increases, and this effect becomes less apparent when the flow velocity reaches a certain threshold. Finally, the flow field characteristics of double cages with different spacing and multiple cages with equal spacing are revealed.
