Singular Boundary Method Analysis of Obliquely Incident Water Wave Passing through Submerged Breakwater
Further to the introduction of radial basis function (RBF) methods given inChapter 1, this chapter presents a brief description of the application of RBF to twodimensionalHelmholtz problems. The background of this chapter is that, in oceanengineering, a submerged breakwater have the advantages of allowing watercirculation, permitting fish passage, and providing economic protection. Therefore,such breakwaters have been widely applied to reduce the energy of transmitted waterwaves. Under the assumption of linear wave theory, the simulation of a water wavepassing through a submerged breakwater can be simplified for solving modifiedHelmholtz equations. In this chapter, the analysis of an oblique incident water wavepassing through a submerged breakwater is taken as the engineering background forinvestigating the use of the singular boundary method for two-dimensional modifiedHelmholtz problems. The origin intensity factors for the 2-D Laplace equation,Helmholtz equation, and modified Helmholtz equation are listed.
