基于WENO格式的高精度高分辨台风风暴潮数值模式
A high-order and high-resolution numerical simulation of storm surge based on the WENO method
摘要
Abstract
Considering the non-linear effects of typhoon storm surge in coastal areas,based on the unstructured meshes,the numerical model of two-dimensional typhoon storm surge was established by using the finite volume method,high-order high-resolution WENO scheme to complete the space discretization of the two-dimensional typhoon storm surge equation,the third-order Runge-Kutta scheme for the time discretization,and the Rogers method to solve the problem of the imbalance between the flux gradient and the discrete source terms,which was caused by the complex submarine topography.Fujita formula and Veno Takeo formula are used to simulate pressure and wind in the model,respectively.At last,through the simulation and verification of the typhoon storm surge along Jiangsu coastal areas,it's proved that the simulation of typhoon storm surge by this numerical model is validity and feasibility.关键词
