A Coupling Model for 3D Nonlinear Wave Propagation from a Numerical Basin to a Physical Wave Basin

摘要

A second-order coupling model is extended to consider 3D nonlinearrnwave propagation in a complete coupling numerical and physical wavernbasin. The first- and second-order solutions for the wave paddle positionrnare obtained by combining the second order coupling theory with thernnonlinear shallow water wave generation theory, in which the waverndirection, non-uniformity and nonlinearity along with the numericalphysical-rnboundary can be completely included. Several comparisonsrnbetween numerical and physical waves have been conducted.rnComparisons of the proposed second order coupling model are alsornmade to the existing first order coupling model. In all experiments, thernresults support the proposed model, which also show that it is capable ofrnsimultaneously processing large-scale numerical wave propagation withrnphysical model including local complex wave phenomena.
