SCATTERING OF WATER WAVES BY VERTICAL CYLINDERS WITH A BACKWALL

Shohachi Kakuno, Kazuki Oda, Philip L.F. Liu

Abstract


The scattering of small amplitude water waves by an array of vertical cylinders with a solid vertical backwall is studied theoretically and experimentally. In the theoretical study, a method of matched asymptotic expansions is developed without considering real fluid effects. The energy loss due to flow separation near cylinders is modeled by introducing a complex blockage coefficient. The theories are compared with laboratory data.
