基于非静压方程的波浪与孔隙结构物相互作用模拟

Simulation of Wave Interaction with Porous Structures Based on Non-Hydrostatic Equation

通过将Darcy-Forchheimer运动方程引入非静压方程中,提出了描述孔隙流体运动的非静压波浪模型.将所建立的数学模型应用到波浪与孔隙结构物相互作用的数值模拟中,并采用物理实验的实验值与数值解进行了对比,结果表明,所建立的模型在垂向只需要较少层数（2～3层）即可合理地描述孔隙结构物前后的波浪变形,为描述波浪与结构物相互作用提供了一种新的解决方案.

A mathematical non-hydrostatic wave model describing pore fluid motion is developed by introducing Darcy-Forchheimer equation into the non-hydrostatic equations. The proposed model is applied to simulating wave interaction with porous structures. Then the model is verified by using experimental data of physical experiments. Results show that the model can describe wave deformation before and after porous structures reasonably with as few as two to three vertical layers. The method provides a new solution to describing wave interaction with structures.
