“…Gansel et al (2011) conducted laboratory tests and field measurements to study the effects of biofouling and fish behavior on the flow field inside and around stocked salmon fish cages. Recently, Bi et al (2014) developed a numerical strategy to study the flow inside and around flexible fish cages by combining the porous-media fluid model and the lumped-mass mechanical model based on their previous study of Zhao et al (2013). Cornejo et al (2014) developed a numerical model to describe the flow velocity downstream of the salmon farm on an incident current with constant and semidiurnal variability.…”

“…The porous-media fluid model is introduced to model the flow field around a plane net (Zhao et al, 2013;Bi et al, 2014), and the finite volume method is used to solve the governing equations of the numerical model. In this way, a numerical model of flow through the biofouled netting can be built.…”

The effect of biofouling on the hydrodynamic characteristics of the net cage is of particular interest as biofouled nettings can significantly reduce flow of well-oxygenated water reaching the stocked fish. For computational efficiency, the porous-media fluid model is proposed to simulate flow through the biofouled plane net and full-scale net cage. The porous coefficients of the porous-media fluid model can be determined from the quadratic-function relationship between the hydrodynamic forces on a plane net and the flow velocity using the least squares method. In this study, drag forces on and flow fields around five plane nets with different levels of biofouling are calculated by use of the proposed model. The numerical results are compared with the experimental data of Swift et al. (2006) and the effectiveness of the numerical model is presented. On that basis, flow through full-scale net cages with the same level of biofouling as the tested plane nets are modeled. The flow fields inside and around biofouled net cages are analyzed and the drag force acting on a net cage is estimated by a control volume analysis method. According to the numerical results, empirical formulas of reduction in flow velocity and load on a net cage are derived as function of drag coefficient of the corresponding biofouled netting.
