Abstract

We investigated the phenomenon of Bragg reflection of submerged structures in a 2D fully nonlinear numerical wave tank (NWT) based on the boundary integral equation method (BIEM). This model was validated by comparing not only the free surface elevations with that of the analytic solution of Stokes' second-order wave theory, but also the reflection coefficients of submerged bars with that from other sources. The results of the present model show that the free surface nonlinear effect on the reflection coefficient of the primary resonance reduces significantly for all of the submerged bars considered. Finally, a case study is presented to demonstrate the reflecting capacity and overall performance of various submerged bars. Results indicate that sinusoidal bar has the maximum reflection capacity at the primary resonance, but the trapezoidal submerged bar is suggested as the better option for the practical convenience of coastal underwater construction.
