具有不均匀水深的全色散Boussinesq模型

Fully dispersive Boussinesq models with uneven bathymetry

John D. Carter, Evgueni Dinvay, Henrik Kalisch

摘要:

研究了三个弱非线性全色散Whitham-Boussinesq系统的非均匀测深问题。对一个系统进行了推导和离散。所有三个的数值解进行了比较,从一系列的实验室实验进行的Dingemans与波计测量。结果表明,尽管这些模型在数学上相似,但它们的准确性差异很大。

英文摘要:

Three weakly nonlinear but fully dispersive Whitham-Boussinesq systems for uneven bathymetry are studied. The derivation and discretization of one system is presented. The numerical solutions of all three are compared with wave gauge measurements from a series of laboratory experiments conducted by Dingemans. The results show that although the models are mathematically similar, their accuracy varies dramatically.
