Abstract
The occurrence of blockages of trash intercepting net in nuclear power plant due to marine biofouling has become increasingly frequent, leading to significant changes in the mechanical state. This paper establishes a CFD (Computational Fluid Dynamics) model to simulate the hydrodynamic forces of trash intercepting net under the action of regular waves. The porous media model is used to calculate the hydrodynamic forces, and the maximum mooring load is also evaluated. The simplified calculation method considering the different curved shape based on the flat nets are proposed, and the influences of wave parameters, solidity, and curved shape are investigated. The results indicate that under the regular wave conditions, as the solidity increases, the phenomenon of secondary wave peaks becomes more pronounced. The horizontal wave force reduction coefficient follows a three-piecewise linear relationship with the non-dimensional deformation level of curved shape. The trash intercepting net exhibits more potent scattering effects on short-wave conditions, displaying significant non-linear characteristics. The deformation level of the trash intercepting net is a significant factor influencing the mooring load.
