| Abstract: | A model for the calculation of velocity reduction behind a fishing net is proposed in this paper. Comparisons are made between the calculated results and experimental data. It is shown that by the application of the effective adjacent area coefficient of fluid flowing around a solid structure to the fishing net, the calculated results agree well with the experimental data. The model proposed in this paper can also be applied to the analysis of the velocity reduction within a fishing cage and can be introduced into the numerical simulation of the hydrodynamic behavior of fishing cages for the improvement of computational accuracy. |
