水波衍射
Examples
- Progress on analytical models for refraction and diffraction of water waves
折射和衍射现象的解析模型的研究进展 - Finite difference method can deal with regular boundary conditions . in this paper , we discrete the water domain into rectangular meshes , and simulate the propagation , reflection and diffraction of water waves . we just specify waves source , the movement of water waves can be simulated automatically
有限差分方法能够处理具有规则边界水域的水流现象，在本文中，我们把求解的水域离散成结构矩形网格，对水流的折射、反射、绕射等水流现象进行了动画模拟，我们仅仅指定产生水流动画的波源，水流动画的细节均由数值方法产生，不需要人工的干预。 - According to different water phenomena , we use two different method to produce waves source : the first method is by specifying the boundary conditions and initialization conditions , this method simulate the dam breaking , reflection and diffraction of water waves ; the second method is by specifying disturbance model , this method simulate water droplets , waterfall , waves of ship ; in the first part of this thesis , we discuss the prevalent methods of the simulation of water scenes , in the second part of this thesis , we describe the numerical methods of solving the shallow water equations using the finite difference method and the finite volume method respectively , in the third part of this thesis , we simulate some realistically liquid phenomena such as rain droplets , the waves of ship , dam breaking etc
产生水波首先要有波源，设置不同的波源便可以得到不同的水流情形，我们用两种方法来产生波源：一种是通过设置边界条件和初始条件产生，这种方法用于模拟溃坝波的反射、折射等现象；另一种是通过扰动控制产生，这种方法用于模拟雨滴、瀑布、船波等自然现象。本论文的第一部分我们讨论了目前水动画模拟常用的几种方法；在第二部分讨论了我们所使用的两类数值方法：有限差分方法和有限体积方法；在第三部分我们模拟了雨滴、船波、溃坝波等一些水流现象。
