Abstract or Summary
  • This report details the derivation of an analytical model for a flexible membrane wave barrier. The wave barrier consists of a thin flexible membrane suspended in the water column by a moored cylindrical buoy on the free surface and fixed to a hinge at the seafloor. The analytical model combines the three-degree of freedom rigid body motion of the cylindrical buoy with the two-dimensional analog of a vibrating string for the response of the flexible membrane. Theoretical results for reflection and transmission coefficients, dynamic mooring line tension, horizontal hinge force, horizontal and vertical displacements and rotation of the cylindrical buoy are compared with measured results presented by Bender(1989). In general, the theoretical results compare favorably with measured results for moored systems. However, additional studies are required to more precisely quantify the added mass and radiation damping properties of flexible membranes in oscillating flows.
