摘要
建立了近岸波浪折射-绕射-破波耗散的有限元数值模式。采用的有限元方法为改进的混合元法,其中外域开边界条件得到改进,内域有限元为伽廖金有限元。用理论解检验了所建立的数值模式,并将该模式应用到一个模型港湾。
The present paper proposes a finite element numerical model for coastal ocean waves with effects of refraction diffraction dissipation due to wave breaking. The adopted numerical method is a modified hybrid element method, in which the open boundary condition is improved in the exterior domain while Galerkin finite element is used in the interior domain. The proposed model is verified by comparison with existing theorectical results. An application to a model harbor is given.
