Bragg reflection of water waves by multiple submerged semi-circular breakwaters
Highlights Bragg reflection of multiple submerged semi-circular breakwaters is studied. Accurate full solutions are developed using multipole expansions. Experimental tests are carried out. Peak reflection coefficient and bandwidth are discussed.
Abstract This study examines the Bragg reflection of water waves by multiple submerged semi-circular breakwaters. The multipole expansions combined with the shift of polar coordinates are used to develop full linear potential solutions of the problem. In the full solutions, the obliquely and normally incident waves are independently considered. Experimental tests are carried out to measure the reflection and transmission coefficients of the breakwaters at different wave periods and body spacings. The analytical results are in reasonable agreement with the experimental data. The peak reflection coefficient of multiple submerged semi-circular breakwaters and the bandwidth of Bragg reflection are carefully examined by numerical examples. Some significant results for practical application are discussed.
