Numerical simulation of the interaction between flow and flexible nets

Three-dimensional deformation of a large circular flexible sea cage in high currents: Field experiment and modeling

“…Other models (Lader and Enerhaug, 2005;Zhao et al, 2007) have been super-elements based and have focused only on the net structures without accounting for the current flow. Another numerical approach based on the joint use of the porous-media model and the lumped-mass model (Bi et al, 2014a(Bi et al, , 2014b has been used to simulate lab-scale experiments. In this article, field measurements of volume reduction in a large-scale fish cage and current reduction inside and behind the cage are presented as well as a numerical method based on these super-elements are presented and used in order to simulate the deformation undergone by the fish cage.…”

Experimental and numerical investigation on the damping effect of net cages in waves

“…It is generally known that a reduction in flow velocity exists downstream from a net cage in current (Aarsnes et al, 1990;Kristiansen and Faltinsen, 2012;Zhao et al, 2013b;Bi et al, 2014a). Similarly, the wave height (or wave energy) will be reduced and the wave geometry will be changed by a net cage due to the damping effect of the fishing net (Lader et al, 2007a;Dong et al, 2008).…”

Development of a Coupled Fluid-Structure Model with Application to a Fishing Net in Current

“…The steady flow field around fishing net can be obtained by using an appropriate iterative scheme as explained later in Section 2.3. This model has been introduced detailed in our previous studies [9][10].…”

“…, can be obtained from the experimental data (see Tables 3 and 4). The corresponding laboratory experiment is presented in our previous study [9]. Porous coefficients are key to the numerical results.…”
