The design of fishing nets can be improved in terms of energy efficiency and selectivity using Computational Fluid Dynamics simulations. Because they are highly flexible and complex structures, geometric simplifications need to be made to reduce the computational cost. This work uses a methodology based on a porous surface model to account for the net. The calibration of the porous coefficients is carried out using experimental measurements on a net sample in a wind tunnel, and the results are validated with CFD computations in OpenFOAM.
