WebMar 23, 2024 · Computational fluid dynamics (CFD) modeling, tow tank and field measurements were used to investigate current flow through and around net panels and cages. For the numerical computations a porous media model was used to represent the net allowing efficient computation of both exterior and interior flow fields. The model was … Webthe biofouling is established. In this study, both constant and tidal currents through a fish farm, consisting of 2×4 full-scale net cages, were investigated numerically. Effects of cage height, incidence angle of the current and level of biofouling on the netting on the flow field in vicinity region of the fish farm were presented and discussed.
