Hydroelastic analysis of wave diffraction by multiple flexible porous plates

Abstract The study investigates the phenomenon of wave diffraction by multiple poroelastic plates in infinitely deep water using two-dimensional linearized potential theory. focuses on numerically computing reflection and transmission coefficients Galerkin approximations specifically designed for two nonidentical vertical plates. By varying separation lengths, porosity, flexural rigidity plates, explores hydrodynamic quantities associated with wave-plate interaction. These are then represented graphically to visualize their behavior under different conditions. results show that porous has a significant effect transmission. correctness method used is confirmed comparing available literature. Overall, provides valuable insights into waves interacting highlights importance considering such systems. numerical approach can also be applied other similar problems provide useful tool predicting complex
