A wave generation boundary with secondary reflection absorption capability is incorporated into the numerical toolbox of the open-source CFD platform OpenFOAM, enabling the construction of a numerical wave flume to simulate regular wave conditions and evaluate the dissipation performance of the proposed breakwater. Comparative analyses are performed against a conventional vertical plate-type permeable breakwater. The investigation systematically examines the variations in transmission, reflection, and dissipation coefficients under different inclination angles and plate curvatures, alongside analyses of the flow field and energy distribution characteristics. The results reveal that the IFP breakwater achieves markedly superior wave dissipation performance compared with the vertical plate-type configuration. As the inclination angle θ increases, the dissipation capacity improves and stabilizes near θ = 30°. Furthermore, greater plate curvature results in a pronounced decrease in the transmission coefficient but simultaneously induces a significant rise in the reflection coefficient. These findings indicate that adjusting the plate curvature can enhance wave energy dissipation, albeit at the expense of increased wave reflection.
